Abstract :
The paper presents a rigorous analysis of rectangular waveguides partially or completely filled with a longitudinally magnetized ferrite (LMF) slab. In these problems, the interface between the dielectric and the ferrite or between the conducting walls and the ferrite represent a discontinuity problem that requires an infinite expansion of waves in each subregion. The analysis is based on the mode matching and the transverse resonance techniques which are combined in such a way as to provide saving in CPU time and memory size requirements. The modes in the ferrite region have, in general, complex propagation constants in the transverse direction. Numerical examples are given for different cases and compared with the published data
