EMP uses the energy generated by chemical fuel combustion to convert it into high-power microwave radiation through microwave devices, which can emit pulsed microwave beams with peak power above GW and frequency of 1 GHz ~ 300 GHz, generating transient voltages of several thousand volts on bare conductors (such as bare wires and printed circuit boards), causing irreparable damage to a large number of electronic equipment.
Principle of electromagnetic pulse
EMP produces negatively charged electrons and extremely strong electromagnetic fields (commonly known as electromagnetic pulses), which may be coupled with electrical equipment or electronic equipment, resulting in destructive currents and surges. The ability of signal interference sensitive circuits requires several attributes. Most microprocessors are composed of field effect transistors (FET) with very low operating voltage. Once the working voltage is too high, catastrophic failure will come.
