Only if you can couple the power into the target in the right way.
Simplest counterexample: Faraday-shielded enclosure. 100KW at 20m
will have no effect on devices inside.
(Then the issue becomes: how good is an automobile as a Faraday cage?
And, what kinds of protection does the circuitry have?)
I plan to make this my one and only response here to this latest
thread. Frankly, the HERF guns and EMP suitcases (a misuse of the
term EMP, in my view, but it's commonly used in this way) have been
discussed many times.
A former and maybe-current member of our list did some contract work
on HERF guns several years back, when the "info war" crowd was
claiming the Irish Republican Army had already launched at least one
attack on London banks.
