Abstract

A quasi-optical Faraday rotation ferrite circulator for microwave or millimeter radiation is analyzed by a matrix formalism. Both reflection and transmission configurations at oblique incidence are examined. Numerical results are presented at 35 degrees and 45 degrees incidence across a band centered at 35 GHz. Calculations are also compared with transmission experiments over a 10% bandwidth. Notwithstanding the complexities of oblique incidence, the reflection-type device promises favorable bandwidth, low loss, and isolation comparable to those of the transmission version now in system deployment, and offers the potential for much higher heat-dissipation capability.<>
