Abstract

First measurements of the reflectivity of different natural and artificial materials in the 600-GHz range are reported. The investigations were carried out using a heterodyne broadband dual-polarization reflectometer in the quasi-optical technique. Compared to Fourier-transform spectrometers this reflectometer is capable of performing real-time measurements even outside the laboratory. Reflectivity data of several interesting materials are presented in co- and crosspolarization.<>
