Tremendously high frequency (THF) is a band designation used by some authors[1] to refer to a decade band in the submillimeter radiation/terahertz radiation range. It follows the ITU EHF band in increasing frequency order.[dubious – discuss]
THF runs the range of frequencies from 300 gigahertz to 3 terahertz, lying in the low (or far) infrared range of the electromagnetic spectrum. The wavelength in this band varies from one to one tenth of a millimetre.
Amateur Radio Service operators do experiments around 322 GHz, 403 GHz and 411 GHz. [2]
