Analysis of inhomogeneously filled cavities by vector finite element method

Accurate analysis of inhomogeneously filled cavities by vector finite element method (VFEM) is presented in this paper. A generalized theory is presented and a tetrahedral subdivision element is exerted for the analysis of inhomogeneously loaded cavities. As a validation, the resonant frequencies of the rectangular and cylindrical cavities filled with dielectric of different types are computed and a comparison with analytical results is made. The examples show excellent flexibility and efficiency of the VFEM method in analysing inhomogeneously filled cavities.
