This thing must use radiation to work. Infrared radiation has a long wavelength on the radiation spectrum. Microwaves are even slower. I would imagine this thing is teetering on the edge of being a microwave gun, but if it only penetrates half a milimetre is probably just a sh*tload of infrared radiation. Either way screw the evil jackbooted nazi b*stards who invented this.
edit: They have had this concept in Warhammer 40K for about 20 years. The Multi-Melta Cannon. Its the most powerful weapon in the game!
