What is an electromagnetic
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.
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.
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
It can destroy Power Grids, Electronics and
Communication System along an entire coast but spare
human and other living species.
In 1925 ,the theory behind the E-bomb was proposed by scientist
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
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
High Power Microwave Device
Explosively pumped Flux Compression
It is a type of generator for producing EMP.
FCG can produce tens of Mega Joules in tens to hundreds of
Peak current of an FCG is 100 times that of a typical lightning stroke.
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
External power source pumps FCG winding with start current
When start current peaks, explosive detonator fired to initiate
Explosive pressure expands armature and creates moving short
Moving armature compresses magnetic field
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 .
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
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
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
Moving short circuit compresses Magnetic Field generates
Intense Electromagnetic burst.
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
Use of motor power isolators for mains
Destroy the delivery vehicle or launch
Hide 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
If you want to see some of the effects of a E-bomb, put your laptop
in your microwave oven (at your own risks).
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.
