Abstract

We present a prototype of a quasioptical Mach—Zehnder interferometer with wave beam splitters in the form of reflective diffraction gratings. Characteristics of the diplexer are studied experimentally at frequencies of about 140 GHz. The measurement results are close to the calculated ones.
