Abstract

A quasi-optical Faraday Rotator for use in beam waveguides with a frequency range of 75-100 GHz has. been developed. The rotator uses a single Samarium-Cobalt (SmCo) ring magnet and a garnet ferrite disk. Fused silica matching layers are placed at the front and back surfaces of the ferrite disk to reduce reflections at the air-ferrite interface. At the design frequency of the matching plates the measured polarization purity, or axial ratio, of the rotated signal is greater than 40 dB and the loss is less than 0.2 dB.
