Abstract

A spectral domain-exponential matrix method is developed for evaluating the dyadic Green´s function for generalized anisotropic substrate-superstrate structures. The method of moments is used to obtain the basic dispersive characteristics of microstrip and inverted microstrip circuits elements on such structures. Results are presented for the propagation constant and characteristic impedance of microstrip elements on generalized anisotropic layers. The investigation of microstrip properties on a biased ferrite-semiconductor interface is emphasized. The model accounts for arbitrarily oriented DC-bias magnetic fields. The phenomenon of forward and backward wave propagation on this type of nonreciprocal structure is highlighted.<>
