A microwave beam weapon is not a fantasy nowadays, it really exists.

It works in the following way: the so-called active denial system (ADS) projects microwave-like radiation even for more than 500 yards. This system makes a painful, full-body burning sensation in someone who got in its rays.

Can you imagine that these millimeter-wave rays permeate skin into a depth of about 1.64in? But the most important aspect is that as the result you get just temporary damages.
