Efficient Recursive Algorithm for Analysis of Anisotropic Microstrip Structures in Multilayer Configuration

A recursive algorithm using suitable choice of trial functions is proposed for adequate analysis of uniaxial anisotropic microstrip type structures in multilayer configuration. The technique is based on the extension of the modal domain integral technique involving the Galerkin's procedure combined with the formalism of mathematical operators. Such approach allows a more efficient resolution of boundary conditions. The efficiency of the proposed algorithm was demonstrated through a successful comparison of the dispersion parameters with published results.
