Quasi-Optical Ring Resonator Diplexf.rs: Theory and Experiment

Abstract

Performance of quasi-optical ring resonator diplexers with plane parallel plate resonator, cylindrical resonator and toroidal resonator mirrors are investigated both theoretically and experimentally. Experimental models have been constructed and tested at 100 GHz. Our results indicate that for diffraction limited cases significant improvement in performance of diplexer may be achieved by utilizing a toroidal reflector properly designed to phase-match the input Gaussian beam from local oscillator.
