Quasi-Optical Reflection Circulator. (Reannouncement with New AvailabilityInformation)

摘要

A quasi-optical Faraday rotation ferrite circulator for microwave or millimeterradiation is analyzed by a matrix formalism. Both reflection and transmission configurations at oblique incidence are examined. Numerical results are presented at 35 deg and 45 deg 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....Quasi-optical circulator, Faraday rotation, Microwave ferrite isolator, Microwave ferrite circulator, Reflection circulator.
