Abstract :
The design and testing of a broadband quasi-optical THz Schottky-diode detector is described. Initial measurements yielded a responsivity of 1000-300 V/W over the frequency range from 150-400 GHz. The effect of the antenna geometry on the performance, and the methods used to calibrate the waveguide and quasi-optical detectors will be described.
