Propagation of electromagnetic waves in elliptical waveguides made of materials with anisotropic Hermitian dielectric tensors

摘要

This paper studies the generalized equations of electromagnetic fields and their solutions in long waveguides with several regions made of materials with Hermitian dielectric tensors and elliptical cross-sections. The special conditions under which the quadratic homogeneous equations of the hybrid modes can be reduced to second-order equations are presented.
