However, for REAL damage, it would be useful to pulse the kilovolts into the magnetron: Generally if you increase the voltage by 10, the power increases by 100. Feed that microwave magnetron with brief (microseconds) pulses of 40,000 volts, rather than 4000, and it will probably generate close to 100 kilowatts. It would be necessary to establish that such a system will not arc with over-voltage, either within the waveguide or the associated high-voltage wiring. high voltage solid state built into shielding around the waveguide/magnetron cavity presents smallest external hazard and compact too. of course, another order-of-mag level up in explosively pumped EW weapons :) http://science.howstuffworks.com/e-bomb3.htm
