FWIW This idea has been around since Viet Nam. I am close friends with an engineer who worked on the project. It used high energy microwaves to deliver about 1 megawatt of RF out of a 6 foot water cooled focused dish. Problem is that it was not mobile and in field testing it exploded anything with water in it out about 500 yards.

This guy swears it was field tested in Nam and since humans were exploding like cats in a microwave the brass didn't think the American public would got for it so the program was shutdown. Also, I believe making it mobile with that power consumption, at that time, would have been impossible. Could of been great for fixed installations though.

Shorten the wavelength even more and you may get a little less damage.
