Cloaking making visible things into invisiblePraDeep Reddy
This document discusses invisibility cloaking technology. It defines cloaking as making visible things invisible using either metamaterials or an invisibility cloak system. There are two types of invisibility cloaking: 1) Using metamaterials to control light reflection properties to make objects invisible, and 2) An invisibility cloak system using a video camera, computer processor, and image projector to project background images to visually replace invisible stationary objects. Potential applications include cloaking military vehicles, making buildings invisible, and improving wireless signals by allowing waves to flow around objects.
This document summarizes a presentation about making technology invisible in the classroom. It discusses the SAMR model for technology integration and enhancing lessons with tools like Poll Everywhere, Today's Meet, and QR code creators. Attendees participated in activities using apps like Toontastic and Educreations to create back-to-school products for students. The document provides resources and examples of how invisible technology can engage students and enhance curriculum without being the main focus.
This document discusses the possibility of invisibility in science. It begins by outlining how invisibility is portrayed in science fiction and then examines whether it could be possible according to the laws of physics. It explores what light is and how it interacts with objects, specifically regarding reflection, absorption, and transmission. The document then covers how light can be bent through refraction and materials called metamaterials that have negative refractive indexes and could potentially bend light around an object to create invisibility. While invisibility is theoretically possible, it is still challenging to accomplish and so far has only been achieved in 2D, but continued technological advances may help realize 3D invisibility.
This document appears to be a script or production notes for a film titled "The Trouble with Invisibility" written and directed by Noa Wiener and produced by Liz Moore. It includes character names like James, Luke and Alex but does not provide much context or plot details in the brief references to "Tone".
This document summarizes the experimental demonstration of an array of 2-D broadband invisibility cloaks that operate in the visible light spectrum. The array was fabricated by coating a microlens array with a thin gold film and pressing it against a gold-coated glass slide. Testing showed the cloaked areas appeared as dark circles surrounded by rings when visible light was passed through. However, the angular performance decayed due to a reduction in symmetry from the light not coinciding with the main axes of the array. This was the first experiment to realize an array of invisibility cloaks operating in the visible frequency range.
The document discusses the results of a study on the effects of exercise on memory and thinking abilities in older adults. The study found that regular exercise can help reduce the decline in thinking abilities that often occurs with age. Specifically, older adults who exercised regularly performed better on tests of memory and decision-making than those who did not exercise regularly.
Invisibility: Theory and Practice - v2John Ashmead
The document is a presentation about invisibility given by John Ashmead at the FOSSCON conference on August 10th, 2013. It covers the history of attempts to achieve invisibility through camouflage and stealth technologies. It also discusses current theories and research regarding invisibility cloaks and manipulating light through metamaterials and transformations of space according to the principles of quantum mechanics and general relativity. The presentation provides both historical context and an overview of the physics behind recent advances in creating invisibility.

This document discusses exposing the invisible or hidden learning that occurs and how technology can help leverage those findings. It encourages looking at various scenarios to identify hidden learning, discussing why it needs to be revealed and how scenarios may be at risk if learning is not exposed. It provides some examples of how technology like annotations, blogs, QR codes, and social media can help share and connect learning. The importance of authenticating, validating, and informing teaching of all student learning and achievements is also covered.
The document outlines two methods for creating invisibility - a manual method using cameras, projectors, and a half mirror, and a scientific method using metamaterials. The scientific method uses metamaterials that can deflect microwaves around an object to create an invisibility effect by influencing the electromagnetic waves. While this technology has applications like more efficient solar panels, its invisibility effect currently only works for a narrow range of wavelengths and moving the material would disrupt the effect. Research continues to improve invisibility cloaking technologies.
This document discusses an invisibility cloak that uses a four lens cloaking device to make objects invisible. It works by using two pairs of convex lenses set up in a straight line, with specific focal lengths and distances between the lenses. As light from the background reflects off the lenses, it refracts in a way that creates "cloaked regions" where background light can pass around an object, making the object invisible. While promising for invisibility, the technology currently has limitations like only working for a single wavelength and not allowing full observer movement. The document outlines ongoing research to develop invisibility at the visible light spectrum and overcome current limitations.
This document discusses the fundamentals of photonic crystals and metamaterials. It defines photonic crystals as periodic optical nanostructures that affect photon motion similarly to how semiconductors affect electrons. Photonic crystals exhibit photonic band gaps where certain wavelengths of light are forbidden to propagate. Metamaterials are designed to interact with optical frequencies and contain nano-resonators that can produce negative permeability at optical frequencies. Challenges in constructing photonic materials at near-infrared and visible wavelengths involve nanoscale fabrication and resonance saturation.
This document summarizes research into biphobia experienced by young bisexual people in the UK. It finds that many bisexual youth experience biphobia regularly, with 33% experiencing it at least monthly. Biphobia comes from both heterosexual and homosexual communities due to stereotypes, such as bisexuals being untrustworthy or confused. The research also showed a lack of legal protections for bisexual people in the UK compared to other groups.
This document provides an overview of metamaterials. It begins by defining metamaterials as materials engineered to have properties that do not occur naturally, such as a negative index of refraction. The document then discusses the history of metamaterials, including early theoretical work in the 1960s and recent developments in fabrication. Examples of potential applications mentioned include invisibility cloaking, subwavelength imaging, and smaller antennas. The document also provides brief descriptions of common metamaterial structures and fabrication techniques using nanostructures like split-ring resonators.
This document discusses metamaterials. Metamaterials are artificial materials engineered to have properties that are not found in nature. They are made of assemblies of multiple conventional elements arranged in periodic patterns which give them properties that depend on geometry rather than chemical composition. Negative refractive index can be achieved when the permeability and permittivity are both negative. Potential applications of metamaterials include invisibility cloaks, superlenses, antennas, and absorbing light. Further work is needed to optimize fabrication processes and characterize more complex 3D metamaterial structures.
Metamaterials are artificial structures designed to have unique electromagnetic properties not found in nature, such as a negative refractive index. They are composed of meta-atoms that can manipulate electromagnetic waves at scales smaller than the wavelength of light. Metamaterials have applications in invisibility cloaking, super lenses, compact antennas, absorbing electromagnetic radiation, and mitigating seismic waves. However, designing metamaterials for specific wavelengths is challenging, and they do not work perfectly and are very expensive.

Metamaterial Course Final Project ( Optional Graduate Course )
Dr. Leyla Yousefi
Metamaterials are artificial materials engineered to have properties not found in nature. They are constructed with repeating patterns of conventional materials like metals and plastics. Electromagnetic metamaterials affect electromagnetic waves through structural features smaller than the wavelength of light or sound. They are classified based on properties like negative index and bandgap. Other metamaterials include elastic and acoustic types that manipulate sound waves. Potential applications include antennas, absorbers, superlenses, cloaking devices, seismic protection, and light/sound filtering.
The document discusses left-handed metamaterials (LHMs) and their applications in microwave engineering. It introduces LHMs, including their defining properties of simultaneous negative permeability and permittivity. It describes two approaches to realizing LHMs - a resonant approach using split-ring resonators and a non-resonant transmission line approach. It then discusses composite right/left-handed metamaterials and their implementation using lumped element unit cells. Finally, it provides examples of metamaterial-based microwave devices like leaky-wave antennas that take advantage of the unique properties of LHMs.
Metamaterials are artificial materials engineered to provide properties not found in nature. They derive their properties from their structure rather than composition. Metamaterials can create negative indexes of refraction and guide waves in desired directions. They have applications in antennas, invisibility cloaking, and frequency selective surfaces. The document discusses the history and types of metamaterials, including electromagnetic and acoustic varieties. It outlines previous work on cubic metamaterials and the presenter's objectives to further explore their properties and applications through modeling and simulation.
Metamaterials are artificial materials engineered to have properties that are not found in nature. They derive their properties from their structure rather than composition. Depending on their structure, metamaterials can have a refractive index less than 1 or even negative refractive index. Left-handed materials have a negative refractive index. While natural materials cannot simultaneously exhibit negative permittivity and permeability, metamaterials can be designed with these properties. Potential applications of metamaterials include antennas, superlenses beyond the diffraction limit, cloaking devices, and modeling conditions of the big bang.
This document discusses meta materials, which are periodic materials that derive their properties from their structure rather than their components. Meta materials are assemblies of microscopic elements arranged in patterns that can affect waves like light and sound in unconventional ways. While the concept was first theorized in the 1940s-1960s, the first experimental demonstrations of functioning electromagnetic meta materials did not occur until 2000. Research on meta materials is interdisciplinary and involves fields like electromagnetics and nanoscience. Potential applications include invisibility cloaking, medical devices, antennas, and sensing and monitoring systems, though developing practical meta material technologies faces challenges around nano-scale fabrication and security concerns.
The document discusses metamaterials and their applications. It begins with defining metamaterials as artificially engineered materials with properties not found in nature. It then discusses techniques for achieving negative permeability and permittivity values, challenges in optical metamaterials, and applications including 3D metamaterials, slow light, cloaking, chiral metamaterials, and superlensing. The talk is divided into sections on different metamaterial topics that will be covered.
This document describes an "Invisible Eye" advanced security system that uses a single camera rather than multiple cameras. It consists of sensors to detect intrusion, a camera mounted on a stepper motor that can slew and take pictures upon alert, and a keypad interface. The system sends SMS alerts to the owner and police if intrusion is detected. It provides security at low cost by avoiding multiple cameras and reviewing hours of empty footage. Potential applications include home, office, and bank security.

Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Must Know Postgres Extension for DBA and Developer during Migration
The ‘Invisibility Cloak’ Antenna Set to Alter the Satellite Market Reality!
1. July-August 2013 6Satellite Executive Briefing
Feature
“Metamaterials is a vast subject. Kymeta is focused on
the application of these new and exotic materials to
make satellite antennas small, mobile, and more af-
fordable,” says Vern Fotheringham, Kymeta’s Chairman,
President and CEO.
A simple Google search on metamaterials leads you to
many stories that border on science fiction. Stanford Report
in an article dated May 6, 2013 describes metamaterials as
engineered (read: manmade) materials that exhibit proper-
ties not found in the natural world. For example, some
metamaterials exhibit a negative index of refraction and
skew the light to the left. Technology that manipulates light
in such unnatural ways could potentially lead to invisibility
cloaks! Properties of these metamaterials to modify the be-
havior of light and radio waves is now being used by Ky-
meta to create a new generation of satellite antennas that
can disrupt not only the satellite industry but the entire tele-
comm industry.
Satellite has some inherent strengths and weaknesses.
While it is the most economical broadcast medium, it is
constrained by the fact that users need to “look at the bird”
with great accuracy to receive service. Satellite antennas are
required to be professionally installed since regulatory
agencies require strict alignment of them to prevent inter-
ference. Such installation requires a costly truck-roll. The
more remote the user is, the greater is the cost of these
truck-rolls. Thus, it seriously blunts the competitive advan-
tage of a satellite as a broadcast medium. This handicap
gets even worse if the user is mobile! Of course, mechanical
steerable satellite antennas exist, but they are bulky, expen-
sive, and difficult to install.
In terms of business economics, heavy investment in ac-
quiring and installing antennas directly affects the customer
acquisition cost for the satellite operator. That, in turn,
negatively impacts operators’ ability to recover vast amount
of capital blocked upfront in building and launching the
satellite infrastructure. Not surprisingly, history of the satel-
lite industry is littered with examples of billions of dollars
of anticlimactic investment that failed to achieve the prom-
ised market penetration at an economically viable cost.
The Kymeta Solution
Kymeta has obtained an exclusive, fully paid, perpetual
global license from Intellectual Ventures for all satellite and
related applications of its Metamaterials Surface Antenna
Technology (MSA-T). It spun off from Intellectual Ven-
tures in August 2012 with backing from marquee investors
including Bill Gates, Lux Capital and Liberty Global.
The ‘Invisibility Cloak’ Antenna
Set to Alter the Satellite
Market Reality

Kymeta’s Portable Laptop-size Satellite Terminal
2. July-August 2013 8Satellite Executive Briefing
Feature
Kymeta’s CTO, Dr. Nathan Kundtz, is a renowned expert in
the field of metamaterials, and has published several papers
on the use of advanced structured materials in beam forming
applications. Under Dr. Kundtz’s technical leadership, Ky-
meta plans to rollout a wide array of antenna products in-
cluding Portable Satellite Terminal (PST), mTenna Core
Module (CM), Aeronautical Terminal, and Fixed Satellite
Terminal. In January of this year, it launched a development
program for Inmarsat,
the global mobile satel-
lite services provider,
with a goal to deliver an
aeronautical antenna
module to provide con-
nectivity for commer-
cial aircraft using In-
marsat’s GlobalXpress
Ka-band mobile com-
munications system. In
April 2013, it achieved
another first by estab-
lishing the first meta-
materials based antenna
connection with a Ka-
band satellite.
A satellite antenna
made from metamateri-
als has several unique
advantages over the
“legacy” products. Here
are the main ones:
Kymeta’s antennas
are the first elec-
tronically steered
beam-forming an-
tennas that replace
mechanical motors
with tunable dielec-
tric metamaterials. It generates a satellite beam by acti-
vating thousands of cells on the panel and changes the
direction of the beams by altering the patterns of these
activated cells. This alters the ‘size-weight-power’ equa-
tion spectacularly. Not only is the Kymeta antenna
smaller and lighter but it requires only a few hundred
milliwatts of power to scan the antenna compared to
tens of kilowatts of power required by phased array an-
tennas.
Kymeta’s antennas are ‘software-driven’ and thus,
highly configurable. These antennas could scan in a con-
tinuous tracking mode or an instantaneous switching
mode, or in a beam lock mode – guided by an underly-
ing satellite tracking algorithm.
Technological Breakthrough: Only a Beginning of
the Disruption
Not all technological innovations result in ‘blockbuster’
products. A blockbuster product is the one that combines the
technological innovation with the market innovation. Indeed,
that is Kymeta’s disruptive potential. Figuratively speaking,
the sky is the only limit!
Of course, a lot will de-
pend on the business deci-
sions that would follow the
completion of technology
development. That is why
the company has enlisted
one of the most innovative
business minds to lead the
team as its CEO & Presi-
dent, Vern Fotheringham.
Vern is a serial entrepre-
neur in the broadband
wireless and satellite com-
munications industry for
over 25 years. He is an
inventor and creator of
innovative new products
and services that are now
adopted as global stan-
dards. He was the Presi-
dent and CEO of ADAP-
TIX, Inc., a world leader in
the development of the
OFDMA technology that is
now the core of the Mobile
WiMAX and LTE broad-
band radio systems.
As is the case with any
technological break-
through, the biggest chal-
lenge Kymeta faces is to
“imagine” a new marketplace for the satellite services that is
not limited by the typical constraints imposed by the legacy
antennas. It will then need to identify and lock-in a range of
strategic alliances with other stakeholders up and down the
value-chain to accelerate its market penetration.
The Tech market metrics in the table (next page) illustrates
how far-reaching an impact Kymeta may have on different
parts of its ecosystem. Of course, it will have to pick and
choose its battles and decide on the beachheads that it needs
to conquer first. “Currently, we are focused towards the high
bandwidth mobile markets that are served by the next-gen
satellites since these are the markets that would appreciate
the value proposition of Kymeta’s solutions most,” says
Vern. As mentioned earlier, Vern’s company is inching
Kymeta’s antennas are the first electronically steered
beam-forming antennas that replace mechanical motors
with tunable dielectric metamaterials. It generates a satel-
lite beam by activating thousands of cells on the panel
and changes the direction of the beams by altering the
patterns of these activated cells. This alters the ‘size-
weight-power’ equation.

closer to deliver-
ing the first Aero
Antenna to In-
marsat by early
2015. Kymeta
Aero Antenna
will enable com-
mercial aircraft
and business jets
of any size to
access high-
speed broadband
c o n n e c t i v i t y
globally through
I n m a r s a t ’ s
Global Xpress
(GX) service.
With the launch
of Aero antenna,
Kymeta will tap
into the rapidly
expanding busi-
ness aviation
market, deliver-
ing business trav-
elers broadband
speeds similar to
what they receive
at their home or
in their office. It also plans to release its commercially avail-
able laptop-sized portable satellite transceiver in the first
quarter of 2015.
However, Kymeta has not been ignoring other opportunities.
It has been working with the start-up fleet operator O3b,
which will launch the first eight satellites of an initial 12-
satellite constellation this year. O3b’s Medium Earth orbit
satellite constellation is designed for Ka-band broadband
applications in the oil and gas exploration, cellular backhaul,
maritime, military and cruise ship markets. O3b can greatly
benefit from Kymeta’s auto-pointing antenna solution giving
them a cost-effective alternative to mechanically steered
infrastructure. Kymeta is also in discussion with various sat-
ellite system operators, to position itself as a means to extend
the useful life of satellites nearing the end of their original
design time, when the gradual loss of onboard station keep-
ing propellant leaves it circling in an inclined orbit.
An antenna is the bridge that connects space and ground seg-
ments of the industry. Full exploitation of the value of these
metamaterial antennas (and consequently, faster prolifera-
tion) will require broader integration with the satellite hubs/
modems on the ground. “We are already in discussions with
all major satellite hub/modem manufacturers,” said Vern. Of
course, hub/modem manufacturers have as much or more to
gain from this innovation as does Kymeta.
Why will Kymeta Succeed?
Kymeta, as any other start-up, faces many demons on its way
to seize the secret treasure. However, no one can deny the
fact that it possesses the ring with the magical powers that
can help it traverse through the difficult terrain … the unique
sustainable customer value proposition!

Executive Spotlight
Kymeta utilizes cutting age technology
in the realm of metamaterials. How do
you manage the age-old innovator’s
dilemma of synchronizing between an
insatiable urge to perfect the technol-
ogy and to be early-to-market with a
product that satisfactorily meets a cus-
tomer need?
Vern Fotheringham (VF): Anyone
productizing a new technology, how-
ever groundbreaking it might be, faces
the same classic dilemma of choosing
between ‘good enough’ [for the market]
and the ‘extraordinary’. At Kymeta, we
face many development tradeoffs as we
race towards market. Ex. Should we
circumvent significant regulatory delays
and be early-to-market with our Re-
ceive-only (RO) fixed antenna solution
or should we, even at the cost of delay-
ing rollout in certain markets, wait to
launch a full-featured two-way antenna
that maximizes the value offered by our
metamaterial antenna? Some of these
tradeoffs would have to be resolved
opportunistically. Key to do so success-
fully lies in the continuous engagement
with the end-user community. We al-
ways have our ears to the ground, lis-
tening carefully to what the end-
consumers’ vital pain-points are and
where our antenna solution can provide
most value. This attention to the market
vibes guides our go-to-market strategy
at every node in our product develop-
ment decision-tree.
Often, a forerunner has a handicap of
having no precedents. In the tech world,
a disruptive technology suffers due to
lack of existing ecosystem. What is the
burden on your shoulders as a pioneer?
VF: Not only do we lack an existing
ecosystem as you suggest but also, we
threaten the legacy ecosystem for the
managed service providers and yes, it
has its own challenges! We are forcing
our industry to imagine a world without
any truck-rolls that has become part of
the industry fabric for so long. One also
needs to revisit all those battlefields that
satellite has ceded to terrestrial wireless
thus far and explore whether we can ‘go
back to the future’! Qualcomm, the pio-
neer in CDMA technology, originally
began as a satellite locating and mes-
saging service – OmniTRACSä, the
first mobile information system for
transportation and logistics. Now, with
Kymeta technology combined with the
high throughput satellites, satellite can
once again become a communication
mode of choice for many mobile appli-
cations. Of course, such disruption al-
ways comes with a burden of meeting
the required quality standards. In case
of mobile communication, we need
build robust situation awareness in our
products to meet the ‘good neighbor’
requirements of avoiding interference
with adjacent satellites.
Kymeta does not have a competitor,
though there are substitutes. In this
context, what market challenges do you
foresee?
VF: Having no competitors is not al-
ways a boon for a start-up like ours.
Since there is not enough volume gen-
erated in the ecosystem, we lack econo-
mies of scale. Producing low-cost high-
volume platform products becomes a
challenge and that, in turn, keeps us
away from tapping into mass market
opportunities as soon as we would like.
Of course, we do offer high value-add
to various niche verticals such as civil
aviation. but our final goal is the mass
market. Another challenge lies in find-
ing the right channel partners to reach
out to the huge market potential that we
offer. An innovative product that may
have numerous hitherto untried applica-
tions also needs an innovative market-
ing approach and development of new
sales channels.
How do you view Kymeta’s impact on
the overall satellite capacity inventory?
VF: Kymeta’s metamaterial antenna
virtually wipes out the distinction be-
tween a mobile and fixed satellite. It
can also be used to put back in service
all that “lost” capacity from the satel-
lites in the inclined orbit. So, without a
doubt, we will add significantly to the
overall
satellite
capacity.
On the
other
hand, we
will also
help the
satellite
operators
to
monetize
much
more of their capacity by enabling
many applications for which satellites
were considered to be inappropriate.
Take example of broadcast overlay ap-
plications. Today, as you are well
aware, we are using Internet traffic ex-
tremely inefficiently with all the one-to-
many bytes transported in the one-to-
one unicast mode. The only way we can
manage this burgeoning internet traffic,
especially in the mobile space, is by
creating a broadcast overlay system.
High throughput satellites with the help
of Kymeta’s antennas can offer such a
service and it will help satellite opera-
tors in-fill their under-utilized beams.
Thus, we will impact both sides of the
satellite economics – demand and sup-
ply.
Today, Kymeta has an exclusive, fully
paid, perpetual global license from In-
tellectual Ventures for all satellite and
related applications. Do you antici-
pate, even if at a distant future, to tap
into markets other than satellites?
VF: The short answer is “no”, not in the
foreseeable future. However, we will
definitely gain some unique insights in
how to commercialize this revolution-
ary technology solution.
How will you define Kymeta’s success?
VF: Isn’t defining the success always
the most difficult problem for an entre-
preneur to address? I have a very sim-
ple answer for you – I will consider
Kymeta a success when it becomes a
household name!
