Terahertz optics

Terahertz optics is a branch of optics and photonics that studies electromagnetic radiation with a wavelength between 0.1 and 1 millimetre, so-called because this corresponds to a frequency of approximately one terahertz (a trillion hertz). Terahertz radiation is relevant for applications in security screening,
