Representations of Green's Dyadics in Multilayered General Faraday Chiral Media

摘要

Studying electromagnetic waves in complex media has been an important research topic due to its useful applications and scientific significance of its physical performance. . In this study, a complete eigenfunction expansion of the dyadic Green's functions for a unbounded and a planar, arbitrary multilayered general Faraday chiral media (both the permittivity and permeability are tensors) are formulated in terms of the vector wave functions in cylindrical coordinates, which is an general extension of the gyroelec-tric cases. After a general representation of the Green's dyadics is obtained, the scattering coefficients of the Green's dyadics are determined from the boundary conditions at each interface and are expressed in a greatly compact form of recurrence matrices.
