Terahertz radiation - Wikipedia
Terahertz radiation – also known as submillimeter radiation, terahertz waves, tremendously high frequency[1] (THF), T-rays, T-waves, T-light, T-lux or THz – consists of electromagnetic waves within the International Telecommunication Union -designated band of frequencies from 0.3 to 3 terahertz (THz), [2] although the upper boundary is somewhat ...
