Negative Refraction
This document discusses metamaterials and their applications in superlensing and cloaking. It begins by explaining Victor Veselago's proposal in the 1960s that a material with negative permeability and permittivity could bend light backwards.

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.

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 Novel Study of Metamaterial and Its Aspects
Stealth knowledge is used to make the object less observable and is defined in terms of absorption of electromagnetic waves that is an important research area used in defence research. Radar cross section is the proportion of the objectives capacity to reflect radar signals toward the radar beneficiary. Some techniques such as shaping, radar absorbing material RAM , passive cancellation and active cancellation have been used for RCS reduction purposes. For a long time, radar absorbing material RAM has been actively pursued. For RAM weight, design, thickness, mechanical strength and absorptivity are key factors and therefore in the development of RAM, there is a trade off between weight and thickness of absorber material. Along with this, an alternative to RAM is RAS and metamaterial are one of the possible options. The metamaterial is lightweight and easy to use. The Stealth property of metamaterial is based on material property i.e., permittivity and permeability of material varying from small positive to large negative values at a particular frequency. In this paper, we hada novel study of metamaterial and its various aspects.

Metamaterials
Meta materials are artificial materials engineered with precise structures that can manipulate waves like light in unconventional ways. Researchers have developed meta materials that bend microwaves but making materials that bend visible light requires even smaller nanoscale structures. Recent work by researchers at the University of California and Imperial College London has created meta materials that can control the direction of light, bringing invisibility cloaks and other applications closer to reality, though challenges remain in developing materials that work across all visible wavelengths.

Javediqbal
Metamaterials are macroscopic composites that exhibit properties not found in nature due to their designed cellular architecture and chemical composition. They allow realization of all possible material properties by designing different cellular structures. The term was coined in 1999. While natural materials occur at discrete points, metamaterials allow realization of most material properties. Their history includes using split-ring resonators to realize negative permeability and perfect lenses. Applications include antennas, cloaking, terahertz modulators, absorbers, and elastic metamaterials. Many predicted linear and nonlinear phenomena remain to be experimentally demonstrated.

This document discusses optical metamaterials and their potential applications. Metamaterials are artificially engineered composites that can exhibit optical properties not found in nature. They are composed of unit cells much smaller than the wavelength of light. By designing the unit cells, metamaterials can have engineered electric permittivity and magnetic permeability values. This allows properties like negative refractive index not found in natural materials. Potential applications discussed include ultrathin lenses and invisibility cloaking by manipulating light propagation.
Scanning Electron Microscope 2
The document discusses scanning electron microscopy (SEM) and its use in characterizing materials. SEM uses an electron beam focused into a probe that scans over a sample, creating signals like secondary electrons and backscattered electrons. These signals are detected and used to form a magnified image of the sample's surface on a cathode ray tube. SEM provides higher magnification than light microscopes, with a greater depth of field. It is capable of elemental analysis and mapping at magnifications from around 10x to 300,000x, with typical operating ranges of 500eV-50keV beam energy.

1. Nanoparticles have unique properties due to their high surface area to volume ratio, including lower melting points and tunable optical absorption.
2. In semiconductors, quantum confinement results from physically constraining electrons, increasing the energy level spacing and causing absorption and emission spectra to shift to higher energies with decreasing particle size.
3. Nanomaterials exhibit both intramolecular bonding like covalent and ionic bonds, and intermolecular bonding like van der Waals forces, which influence their physical and chemical properties.
Nano meta materials
Nanomaterials are characterized by at least one dimension in the nanometer range. Their properties differ from bulk materials due to two main factors: increased surface area and quantum effects. These factors can enhance properties such as reactivity, strength, and electrical characteristics. Metamaterials are artificial materials engineered to have properties not found in nature.

Metamaterials can manipulate electromagnetic waves in ways not possible with conventional materials, such as achieving a negative index of refraction. Potential applications include invisibility cloaks, improved telecommunications and solar cells.
Photonic Materials
Photonic materials manipulate photons to achieve certain functions. Photonic crystals are a type of photonic material that displays unusual properties in interacting with light due to a periodic modulation of refractive index.

Photonic crystals can manipulate light signals and guide them through solid structures. They are periodic lattice structures that can create photonic band gaps to control the paths of particular light frequencies. Surface wave guides use nanostructured metal surfaces to direct photon beams along paths between regular arrays, with surface plasmons guiding the light. Photonic crystals have applications in fiber optic communication, single mode LEDs, lasers, optical devices, fast electronics, and medical therapy. They represent the future of semiconductors and will have wide cross-field applications due to their ability to transport energy as photons rather than electrons.

What is Cathodoluminescence? - DELMIC
In cathodoluminescence imaging, an electron beam is used to excite nanostructures and the cathodoluminescence detector is subsequently used to detect the produced light.
Cathodoluminescence emission can be used to explore many fundamental properties of matter. It can be used to study light transport, scattering, electronic structure of a material, resonant phenomena and much more. It thus presents a valuable source of information for fundamental research as well as applied research with a direct link to industry.
The SPARC is a high-performance cathodoluminescence detection system that is designed and produced by Delmic. With this system, Delmic offers a unique solution for cathodoluminescence imaging.
In this presentation, we share the knowledge about the cathodoluminescence technique and point out the key advantages of using cathodoluminescence imaging in different areas.
For questions about cathodoluminescence and the SPARC, please leave a comment below or visit www.delmic.com and send us a message.
Nanowires - Physics for Growth of Nanostructure
In this article, we are introducing some technique of growth Nanowire for Nanostructures for physics, A Nanowire considered as a Nanostructure which is build blocks for the generation of electrons protons neutrons positions and the sensor and also the energy applications. In this project, we are to synthesis and growth of semiconductor nanowire made by metallic both of the axial and radial structure and their properties discuss here. In one-dimensional nanostructure of control, density States turned into the electronic and optic properties. There is a new technique of growth metallic and semiconducting material develop in the International Science. A nanowire is a nanostructure, with the diameter of the order of a nanometer (10−9 meters) and an unconstrained length. At these scales, quantum mechanical effects are important — which coined the term "quantum wires.” Quantum confinement produces new material behaviour/phenomena. Based on the degree of confinement different Structures arise.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdf
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

META-MATERIALS : AN OVERVIEW
- 1. BASAV PRASAD 19BEC0588 META-MATERIALS : AN OVERVIEW DIGITAL ASSIGNMENT – 2 NAME: BASAV PRASAD REG.NO: 19BEC0588 COURSE: INTRODUCTION TO NANOSCIENCE AND NANOTECHNOLOGY COURSE CODE: ECE1006 COURSE FACULTY: MUTHU RAJA S
- 2. BASAV PRASAD 19BEC0588 INTRODUCTION • This word is a combination of “meta” and “material”, Meta is a Greek word which means something beyond, altered, or changed. • Metamaterials are artificial materials engineered to have properties that have not yet been found in nature. They are assemblies of multiple individual elements fashioned from conventional materials such as metals or plastics, but the materials are usually constructed into repeating patterns, often with microscopic structures. • Metamaterials derive their properties not from the compositional properties of the base materials, but from their exactingly-designed structures. Their precise shape, geometry, size, orientation and arrangement can affect waves of light (electromagnetic radiation) or sound in a manner not observed in natural materials.
- 3. BASAV PRASAD 19BEC0588 PROPERTIES OF META-MATERIALS • All "natural" materials like glass, or diamond have positive electrical permittivity, magnetic permeability and an index of refraction. In these new artificially fabricated materials – called negative index materials (NIM) or double negative (ONG) media or left handed (LH) materials or backward wave (BW) media - all these material parameters are negative. • The electrical permittivity and the magnetic permeability are the main determinants of a material's response to electromagnetic (EM) waves. In metamaterials, both these material parameters are negative. • Correspondingly, the refractive index of the metamaterials is also negative. • Another strange property of metamaterials is its reverse Doppler effect.
- 4. BASAV PRASAD 19BEC0588 APPLICATIONS 1. Metamaterial antenna: • Some of their advantages are: High gain, electrically configurable, Ultra-fast reconfiguration, Self- alignment, Active dynamic null generation, Lightweight. 2. Cloaking Device: • The purpose of a cloaking device is to hide something, so that a defined region of space is invisibly isolated from passing electromagnetic fields, as with Metamaterial cloaking. • The object doesn't really disappear; the vanishing is an illusion.
- 5. BASAV PRASAD 19BEC0588 3. Super-lens: • The imaging resolution of conventional lenses is limited by diffraction. Artificially engineered metamaterials now offer the possibility of building a super-lens that overcomes this limit. • A practical superlens, is a lens which uses metamaterials to go beyond the diffraction limit. 4. Perfect absorber of light: • Researchers have engineered a new metamaterial that uses its unique geometric surface features to "perfectly" absorb all of the electric and magnetic properties of a microwave. Resonators couple individually to electric and magnetic fields to absorb all incident radiation. 5. Metamaterials for solar cells: • The new metamaterial is particularly well suited to use in solar cells.
- 6. BASAV PRASAD 19BEC0588 • Scientists could potentially tune its index response to better match the solar spectrum, allowing for the development of broadband wide-angle metamaterials that could enhance light collection in solar cells. • And the fact that the metamaterial has a wide-angle response is important because it means that it can 'accept' light from a broad range of angles. In the case of solar cells, this means more light collection and less reflected or 'wasted' light. I PERSONALLY THINK THAT THE IDEA SHOWN IN THE PICTURE ASIDE WILL BE POSSIBLE SOON.
