An electromagnetic bomb, or E-bomb, is a weapon that generates a powerful electromagnetic pulse capable of disabling electronics over a wide area without harming people. It works by using an explosively-pumped flux compression generator or high power microwave device to generate an intense electromagnetic burst. This electromagnetic pulse induces damaging voltages in exposed wiring and circuitry. While an E-bomb could knock out power grids and communication systems across an entire coast, it has limitations in accuracy and risks harming medical equipment. There is ongoing research focused on developing more advanced E-bomb technologies and defenses against electromagnetic weapons.

5. What is an electromagnetic
bomb………………..?????
An electromagnetic bomb or E-bomb is a weapon
designed to disable electronics with an electromagnetic
pulse (EMP) that can couple with electrical/electronic
systems to produce damaging current.

6.  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.

7. History
In 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.

8. 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.

9. E-Bomb Technology Base:
 Power source : Battery, Capacitor bank
 Explosively pumped Flux Compression
Generator (FCG).
 High Power Microwave Device
 Antenna

11. Explosively pumped Flux Compression
Generator (FCG)
 It is a type of generator for producing EMP.
 FCG can produce tens of Mega Joules in tens to hundreds of
microseconds.
 Peak current of an FCG is 100 times that of a typical lightning stroke.

12. FCG Internals:
 Armature - copper tube / fast explosive
 Stator - helical heavy wire coil
 Initiator - plane wave explosive detonator
 Jacket - prevents disintegration due magnetic forces
Consists : Metal cylinder (called the armature), surrounded by
a coil of wire (the stator winding). The armature cylinder is filled
with high explosive, and a sturdy jacket surrounds the entire
device.

13. Design of FCG

14. 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

16.  Whilst FCGs are patent technology base for the generation of large
electrical power pulses, the output of the FCG is by its basic physics
constrained to the frequency band below 1 MHz
 Many target sets will be difficult to attack even with very high power
levels at such frequencies.
 A HPM device overcomes the problems, as its output power may be
tightly focused and it has a much better ability to couple energy into
many target .
Contd…..

17.  The fundamental idea behind the HPM is to amplify the resulting
electromagnetic burst into high power microwave
The principle of the vircator is that of accelerating a high Current
electron beam against a mesh (or foil) anode.
 Many electrons will pass through the anode, forming a bubble of
Space charge behind the anode. This space charge region Will oscillate at
microwave frequencies.
 If the space charge region is placed in to resonant cavity which is
appropriately tuned very high peak powers may be achieved.
High Power Microwave Sources – The Vircator

19. 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.

20. Contd…..

22. 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

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

24. Protection/defense against electromagnetic
bomb
Faraday cage
Site hardening
Use of motor power isolators for mains
power distribution
Destroy the delivery vehicle or launch
platform
Hide important assets

25. 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.

26. 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

27.  If you want to see some of the effects of a E-bomb, put your laptop
in your microwave oven (at your own risks).

28. Conclusions:
 Electromagnetic bombs are Weapons of Electrical Mass Destruction
with applications across a broad spectrum of targets, spanning both the
strategic and tactical.
 E-bombs can cause hard electrical kills over larger areas than
conventional explosive weapons of similar mass.
 The E-bomb is a Useful punitive Weapon as it can cause much
economic and military damage with no loss of civilian life.
 E-bomb could be profitably used against countries which sponsor
terrorism and info-terrorism.
