Shock wave generators are capable of producing focused acoustic or electromagnetic energy that can break up objects such as kidney stones and other similar materials. EMP generators can produce pulses of electromagnetic energy that can destroy the sensitive electronics in computers and microprocessors. Destabilized LCR circuits can produce multi megawatt pulses by using an explosive wire disruptive switch. These high power pulses can be coupled into antennas, conic sections, horns etc for very directional effects. Research is currently being undertaken to disable vehicles thus avoiding dangerous high speed chases. The trick is to generate a high enough power pulse to fry the electronic control processor modules. This could be a lot simpler if the vehicle was covered in plastic or fiber glass rather than metal. The shielding of the metal body offers a challenge to the researcher to develop a practical system. A system could be built that could do this but would be costly, large and produce collateral damage to friendly targets.
