Spectral domain technique for the analysis of waveguide junction with anisotropic media

A rigorous analysis of a waveguide junction with lossy arbitrarily shaped anisotropic media is proposed. The analysis is based on the equivalence principle and the spectral domain technique and depends neither on the geometrical symmetry of the junction nor on the number of ports. To demonstrate the validity of the method, H- and E-plane Y-junction circulators are considered. The effects of magnetic and dielectric losses on the performance of the circulators are examined.<>
