Extremely High Frequency

Extremely high frequency (EHF) is the ITU designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz, above which electromagnetic radiation is considered to be low (or far) infrared light, also referred to as terahertz radiation. Radio waves in this band have wavelengths from ten to one millimetre, giving it the name millimetre band or millimetre wave, sometimes abbreviated MMW or mmW. Millimetre length electromagnetic waves were first investigated in the 1890s by pioneering Indian scientist Jagadish Chandra Bose. Extremely High Frequency, Wikipedia
