The document describes an electromagnetic bomb (E-bomb) that uses an explosively pumped flux compression generator (FCG) to produce high currents and electromagnetic pulses. The FCG uses an explosive lens to compress a magnetic field within a copper armature, transferring mechanical energy into electrical energy. This allows the E-bomb to generate tens of megajoules in microseconds. When coupled with a vircator, which produces high power microwaves, the E-bomb becomes a weapon of electrical mass destruction capable of destroying semiconductor electronics over large areas with low collateral damage. The document argues that E-bombs could provide strategic advantages in future conflicts by paralyzing infrastructure through non-lethal means.

Hybrid Power System is the integration of number of generating plants those are working together serve a particular region. They may be off grid or may not be.
Virtual keyboard
A virtual keyboard is a software component that allows a user to enter characters.[1] A virtual keyboard can usually be operated with multiple input devices, which may include a touchscreen, an actual computer keyboard and a computer mouse.
An optical virtual keyboard was invented and patented by IBM engineers in 2008.[6] It optically detects and analyses human hand and finger motions and interprets them as operations on a physically non-existent input device like a surface having painted keys. In that way it allows to emulate unlimited types of manually operated input devices such as a mouse or keyboard. All mechanical input units can be replaced by such virtual devices, optimized for the current application and for the user's physiology maintaining speed, simplicity and unambiguity of manual data input.
An e-bomb (electromagnetic bomb) is a weapon that uses an intense electromagnetic field to create a brief pulse of energy that affects electronic circuitry without harming humans or buildings. At low levels, the pulse temporarily disables electronics systems; mid-range levels corrupt computer data.

After decade of research and development, Directed energy weapon are become an operational reality. Such weapons generate streams of electromagnetic energy that can precisely aimed over long distance to disable or destroy target. It is game changing technology in future.
Eelctro-Magnetic-Pulse USE AS A WEAPONAshutosh Uke
Seminar Report File - High Power Electromagnetic Pulse generation techniques and High Power Microwave technology have matured to the point where practical EMP Weapon (Electromagnetic pulse) are becoming technically feasible, with new applications in both Strategic and Tactical Information Warfare. The development of conventional EMP devices allows their use in non-nuclear confrontations. This paper discusses aspects of the technology base, weapon delivery techniques and proposes a doctrinal foundation for the use of such devices in warhead and bomb applications.
Green computing is the environmentally responsible and eco-friendly use of computers and their resources. In broader terms, it is also defined as the study of designing, manufacturing/engineering, using and disposing of computing devices in a way that reduces their environmental impact.
Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., computer networks, servers, storage, applications and services),

Artificial intelligence (AI) is intelligence exhibited by machines. In computer science, the field of AI research defines itself as the study of "intelligent agents". Robotics is the interdisciplinary branch of engineering and science that includes mechanical engineering, electrical engineering, computer science, and others.

Robotics is the interdisciplinary branch of engineering and science that includes mechanical engineering, electrical engineering, computer science, and others. Robotics deals with the design, construction, operation, and use of robots,[1] as well as computer systems for their control, sensory feedback, and information processing.
Light Fidelity (Li-Fi) is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas[1] and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or even a replacement in contexts of data broadcasting.
1. THE E- BOMB
A WEAPON OF ELECTRICAL
MASS DESTRUCTION
by Megha Pradhan
Department of Electrical Engineering
2. INTRODUCTION:
Desert Storm Counter-C3 operations relied on air power
and precision guided munitions
Future campaigns will require more suitable weapons to
achieve shock effect over large target sets with small
attacking forces
Electromagnetic bombs (E-bombs) can perform such a
role
3.
4. E-BOMB TECHNOLOGY BASE
Power source - explosively pumped Flux Compression
Generator (FCG)
FCG pioneered by Los Alamos Labs during the 1950s
FCG can produce tens of Mega Joules in tens to
hundreds of microseconds
Peak current of an FCG is 1000 X that of a typical
lightning stroke
5. THE PHYSICS OF THE FCG:
Fast explosive compresses a magnetic field
Compression transfers mechanical energy into the
magnetic field
Peak currents of Mega Amperes demonstrated in many
experiments
6. FCG START CURRENT IS PROVIDED
BY AN EXTERNAL SOURCE
capacitor bank
small FCG
MHD device
homopolar generator
7.
8.
9. FCG INTERNALS:
Armature - copper tube / fast explosive
Stator - helical heavy wire coil
Initiator - plane wave explosive lens
Jacket - prevents disintegration due magnetic forces
10. FCG OPERATION:
External power source pumps FCG winding with start
current
When start current peaks, explosive lens fired to
initiate explosive burn
Explosive pressure expands armature and creates
moving short
Moving armature compresses magnetic field
11. HIGH POWER MICROWAVE (HPM)
SOURCES:
Higher lethality than low frequency FCG fields, many
device types:
Relativistic Klystrons
Magnetrons
Slow Wave Devices
Reflex Triodes
Virtual Cathode Oscillators (vircators)
12.
13. VIRCATOR PHYSICS:
Relativistic electron beam punches through foil or
mesh anode
”Virtual” cathode formed by space charge bubble
behind anode
Peak power of tens of GW for 100s of nsec
Anode typically melts in about 1 usec
Cheap and simple to manufacture
Wide bandwidth allows chirping of oscillation
14. LETHALITY ISSUES IN E-
BOMB WARHEADS:
Diversity of target set makes prediction of lethality
difficult
Different implementations of like equipment have
differing hardness
Coupling efficiency is critical to lethality
15. SEMICONDUCTOR VULNERABILITY:
Semiconductor components using CMOS, RF Bipolar,
RF GaAs, NMOS DRAM processes are destroyed by
exposure to volts to tens of volts of electrical voltage
High speed - high density semiconductors are highly
vulnerable due small junction sizes and low
breakdown voltages
16. DELIVERY OF E-BOMBS:
Warhead comprises priming current source, FCG
(cascade) and Vircator tube
Missile installations must supply 100% of weapon
priming energy from own supply
Bomb installations - weapon can be precharged before
release from aircraft
A free fall E-bomb is more lethal than a missile borne
HPM warhead as a larger proportion of the weapon is
the warhead

19. E-BOMB ADVANTAGES IN STRATEGIC
WARFARE
Not lethal to humans
Negligible collateral damage
No mass media coverage of bombing casualties
(broadcast eqpt destroyed) will reduce the threshold
for the use of strategic air power and missile forces
20. CONCLUSIONS:
The E-bomb is a Weapon of Electrical Mass
Destruction
High payoff in using E-bombs against fundamental
infrastructure, resulting in substantial paralysis
E-bombs will become a decisive capability in Strategic
Warfare and Electronic Combat
E-bombs are a non-lethal weapon
The critical issues for the next decade are the
deployment of E-bombs and the hardening of
fundamental infrastructure
