Dispersion in the microwave planar dispositif with ferrite

In this paper, a rigorous study of the formulation of the transverse operator method (TOM) is described for studying general propagating structures with transverse inhomogeneity and anisotropy. The dispersion characteristics of some multi-dielectric waveguide structures have been obtained. Other dielectric waveguides with arbitrary cross-sections can be studied by using this procedure with no modifications. The advantage of this method is that it has a fast convergence. The results are compared to those previously published and show a good agreement. The results presented here show that not only the transverse operator formulation is an elegant theoretical form, but it is also a powerful and efficient analysis method, it is useful to solve a number of the propagation problems in electromagnetics.
