Joint use of generalized scattering matrices and domains' product technique in theory of complicated planar waveguide structures

A technique of utilization of generalized scattering matrices (S-matrices) for numerical analysis of H-and E-plane waveguide transforms having polygonal boundaries and piece-wise homogeneous filler is developed. The method of decomposition of such objects, providing the possibility of calculating S-matrices of isolated autonomous blocks by means of the domains' product (DP) method, has been proposed. Some illustrative examples are considered.
