6th AUGUST IN HIROSHIMA AROUND 166000 DIED BECAUSE OF THE ATOM BOMB ATTACK BY AMERICA

9th AUGUST IN NAGASAKI AROUND 90000 DIED IN THE SECOND ATTACK

DOES WAR MEAN ONLY

KILLINGPEOPLE…?

What is an

ElectroMagnetic Bomb………???

“An electromagnetic bomb or EM-bomb is a weapon designedto disable electronics with an electromagnetic pulse (EMP) thatcan couple with electrical/electronic systems to producedamaging current.”

Basic Principle of EM-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.

Explosively pumped Flux Compression Generator (FCG)

• It is a type of generator for producing EMP.

• FCG can produce tens of Mega Joules of energy in tens

to hundreds of microseconds.

• Peak current of an FCG is 1000 times that of a typical

lightning stroke.

High Power Microwave Sources – The Vircator

• 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.

Defense against ElectroMagnetic Bomb

• Faraday cage

• Site hardening

• Hide important assets

• Destroy the delivery vehicle or launch platform

Advantages of ElectroMagnetic Bomb

• Permanently 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 generators or cars.

• It can destroy Power Grids and Electronics System

along an entire coast but spares human and other

living species.

Limitations of ElectroMagnetic Bomb

• 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.

Conclusions

EM-bomb can cause hard electrical kills over larger

areas than conventional explosive weapons of similar

mass.

The EM-bomb is a useful punitive weapon as it can

cause much economic and military damage with no loss

of civilian life.

EM-bomb could be profitably used against countries

which sponsor terrorism and info-terrorism.
