The paper presents an analysis of a slit in a dielectric coated ground plane backed by a 2D cavity. The cavity can be inhomogeneously filled with anisotropic material, and the dielectric coating can contain a perfectly conducting strip. A fullwave frequency domain model is developed wherein finite elements are coupled with the spectral domain method of moments. The method is- validated through comparisons to results generated by other fullwave models. Convergence results for different finite element types are studied. Theoretical results for cavities partially filled with ferrite material are generated. Specifically, the effect of the DC magnetic bias field on ferrite material is studied.
