FULL-WAVE ANALYSIS OF A TRANSVERSELY MAGNETIZED FERRITE NONRADIATIVE DIELECTRIC WAVE-GUIDE

A full-wave analysis is applied to a nonradiative dielectric waveguide where the isotropic dielectric slab is replaced by a transversely magnetized ferrite. The characteristic equation is obtained and the corresponding effects are discussed. The above structure exhibits reciprocal propagation characteristics. Nonreciprocal effects are also possible with a proper dielectric loading. Several numerical results are presented in the form of dispersion curves and operational diagram, as function of several ferrite and guide parameters. Electronically tuned and nonreciprocal devices can be implemented using this simple structure.41464765
