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.
