Abstract:
In this paper, a rigorous study of rectangular waveguide partially filled with longitudinally magnetized ferrite is presented. The propagation constant as a function of frequency is first obtained by the use of Transverse Operator Method. We show the existence of the complex modes in this type of structures with ferrite. In these problems, the interface between an air filled rectangular waveguide and E-plane ferrite slab loaded rectangular waveguide represent a discontinuity problem. The analysis is based on the Mode Matching Method and the Transverse Operator Method which are combined in such a way as to determine the scattering parameters. The proposed approach is validated by comparing the presented results with the published data and numerical ones obtained from commercial software.
