Abstract
A radiation sensor that can operate in the THz regime comprising: a micro antenna, which may comprise a two-dimensional patterned thin-film metallizations on a thin dielectric pellicle fabricated by micro machining of a silicon wafer; a thermally isolated microstructure; a coupling mechanism for coupling the energy from the micro antenna to the microstructure, the coupling mechanism providing high thermal isolation between the micro antenna and the microstructure; a temperature signal detector on the microstructure; and signal processing electronics for receiving the temperature signal and processing it into useful data.
