Terahertz (THz) electromagnetic waves have frequencies of order 10^12 Hz and wavelengths in the range of 100 micrometers. Terahertz spectroscopy for material imaging/sensing and characterization has received a great deal of attention over the past decade. It has been shown that many materials including organic materials, explosives, pharmaceutical compounds and biological agents have distinct signatures in the terahertz frequencies. Consequently, THz technology has many potential applications in areas such as pharmaceutical industry, food industry, organic light emitters manufacturing, security, aerospace, oil industry, medical imaging, medicine, as well as ultra-high-data-rate wireless communications. The distinct characteristics of THz radiation, along with recent advances in the enabling technologies behind, have created the opportunity for the terahertz technology to provide unique solutions to many critical industrial problems.
