Abstract

Development of a reflection circulator designed for use in quasi-optical beam systems is reported. Requirements of a millimeter-wave radar motivated the project, but the attractive performance features of the device, including broad bandwidth and high power capability, make it suitable for other applications as well. The discussion includes the underlying principle of nonreciprocity, problems of Faraday rotation, refraction, and polarization- insensitive anti-reflection matching at oblique angles of propagation. Comparisons of experimental measurements with a computational model show excellent agreement.
