A Unified Treatment of Edge-Guided Waves.

Abstract

Edge-guided waves (EGW) are electromagnetic waves guided by the RF conductor edge of a ferrite stripline or microstrip circuit magnetized perpendicularly to the ground plane. EGW multi-octave isolators and circulators as well as nonreciprocal phase shifters have been constructed and used in operational systems. This report presents in a unified fashion and in a single text the results of the theoretical work on EGW propagation. Magnetic losses and a finite edge impedance are considered and shown to be responsible for the limitations on the broadband behavior of EGWs. Dielectric loading and curvature of the guiding edge, as well as fringing field effects, are also studied. (Author)
