As of August 2012, a millimeter wave full body scanner is in use.

And when that fails, you'll talk about building some paraboloid with a free-flying feed in Earth orbit so you can get millimeter waves.

Their total frequency range was from visible light down to millimeter waves.

The idea is that the millimeter waves don't penetrate far into the skin, so no permanent damage results.

Such systems use very high-frequency radar propagations called millimeter waves, which greatly reduce the size and energy of side lobes.

It produced the first manmade coherent infrared radiation, having a total frequency range was from visible light down to millimeter waves.

Note that frequencies above 30 GHz are typically said to be in the "millimeter wave".

Water vapor emits millimeter waves similar to the cosmic background radiation.

Research resumed in solid state devices, plasma physics, millimeter waves, and integrated circuits.

With active scanners, the millimeter wave is transmitted from two antennas simultaneously as they rotate around the body.
