Extremely high frequency: Music, History, Applications & Career

Extremely high frequency (EHF) is the electromagnetic band from 30 to 300 gigahertz (GHz), as designated by the International Telecommunication Union (ITU) designation. It is in the microwave part of the radio spectrum, between the super high frequency band and the terahertz band. Radio waves in this band have wavelengths from ten to one millimeter (10–1…
