It would be interesting to see the data (and the logic) of prior Pentagon
testing which led to the choice of 95 GHz by the military.
If you just wanted to find the best frequency for RF heating of water at lowest
cost - that would probably be the resonance or "water line" seen in cosmology
at 22 GHz and several higher values ... but not at 95 GHz. It seems like a bad
choice on the surface.
Consequently, the choice is suspicious in itself since in general there are
silicon solutions that can exploit the lower value but not so much at the
higher. Probably the choice has something to do with Cree (just a guess).
Or more likely - the real aim is not "crowd control" at all.

Thanks. The claim in the marketing blurb of 'penetrating the skin to a depth of
only about 1/64th of an inch', if approximately accurate, suggests a highly
efficient dielectric heating effect, then. Compare with lower frequencies: for
example, a mobile phone at around 2 GHz will heat the brain and eyeball as well
as the ear, while at 95 GHz it seems that most of the energy is converted to
heat in a thin slice of skin, presumably with a much more concentrated cellular
impact.

The energy transfer is via dielectric heating of fats and water, just as in a
microwave oven.
