 Terahertz spectroscopy and technology

Terahertz (THz) spectroscopy and technology are fields that study electromagnetic radiation in the terahertz frequency range, typically defined as frequencies from 0.1 THz to 10 THz (or wavelengths from about 3 mm to 30 µm). This region lies between the microwave and infrared regions of the electromagnetic spectrum and has gained considerable interest for various scientific and technological applications.
