WHAT IS E-BOMB?(ELECTROMAGNETIC BOMB)

It is weapon of Electrical Mass Disruption

It is based on Electromagnet- tic Pulse Theory

This weapon change magnetic field which couple with electric circuitry to produce damage currents surges

An Electromagnetic Pulse Bomb (or EMP) is a non-lethal, but highly destructive, weapon that emits an electromagnetic pulse that disables all electrical circuitry within a certain radius.

INTRODUCTION :

In a matter of seconds, a big enough e-bomb could thrust an entire city back 200 years or cripple a military unit.

An e-bomb is a weapon designed to take advantage of cutting of power in an area, destroying of machines that use electricity. It can destroy Power Grids, Electronics and Communication System along an entire coast but spare human and other living species.

HistoryIn 1925 ,the theory behind the E-bomb was proposed by scientist Arther.H.Compton.

In 1940, the existence of the Electromagnetic Pulse was observed.

In 1998 , David Schriner a electrical engineer in US navy developed a E-bomb whose effect cover circular area having 15 meter radius.

In 2000 ,British scientist Bae Dynamics developed an E-bomb that could destroy electrical and electronics system for miles.

Presently Russia ,USA ,England are equipped with this electromagnetic weapon

In Asia India is the only country to have e-bomb.

Basic Principle of E-bomb

The Electromagnetic pulse (Emp) effect.

The Electromagnetic Pulse is an electromagnetic shock wave.

This pulse of energy produces a powerful electromagnetic field sufficiently strong to produce short lived transient voltages of thousands of Volts (i.e. kilovolts) on exposed electrical conductors like wires ,printed circuit boards etc.

E-Bomb Technology Base: Power source : Battery, Capacitor bank

Explosively pumped Flux Compression Generator (FCG).

High Power Microwave Device

Antenna

Design of FCG

FCG Operation:

External power source pumps FCG winding with start current

When start current peaks, explosive detonator fired to initiate explosive burn

Explosive pressure expands armature and creates moving short

Moving armature compresses magnetic field

Operation Of E-bomb Capacitors connects to Stator sets electrical current through wires Generates Intense Magnetic Field.

Fuse mechanism ignites the explosive material Explosion travels as wave through the middle of the armature cylinder. Explosion passes through cylinder Cylinder comes in contact with stator winding creates a short circuit cuts the stator off from its power supply.

Moving short circuit compresses Magnetic Field generates Intense Electromagnetic burst.

COUPLING MODES.. Front Door Coupling occurs typically when power from an electromagnetic weapon is coupled into an antenna associated with radar or communications equipment . Back Door Coupling through power/data cabling, telephone wiring and destroys exposed semiconductor devices

THE DELIVERY OF CONVENTIONAL E-BOMBS: Electromagnetic warheads may be fitted to range of delivery vehicles.

Protection/defense against electromagnetic bomb

Faraday cageSite hardeningUse of motor power isolators for mains power distributionDestroy the delivery vehicle or launch platformHide important assets

Advantages of E-bomb Permanent damages the electrical appliances such as computers and micro processor devices.

Easy to diffuse or to destroy the missiles.

Destroys the communication system.

It can even stop working of generator or cars.

It can destroy Power Grids and Electronics System along an entire coast but spare human and other living species.

Limitations of Electromagnetic Bombs The limitations of electromagnetic weapons are determined by ,

* Weapon implementation

* Means of delivery Accuracy of delivery and achievable range must be considered against the allowable damage for the chosen target. An inaccurately delivered weapon of large range may be unusable against a target . Patients who are on the ventilation in hospital or using pacemaker may lose there life because of no electric power
