Sub-Terahertz Wave Detection of Foreign Matter in Filling Containers

Proceedings
In recent years, electromagnetic waves (terahertz waves) with frequencies between 0.1 and 10 THz, which exist between radio waves and light waves, have attracted much attention.

Active gas sensing with sub-terahertz waves reflected from a wall

, 2008
We present active gas sensing with a sub-terahertz (THz) spectrometer. The transmitter and receiver of the system are composed of a photonic-base source and a Schottky barrier detector, respectively, and their arrangement is monostatic.
