Dyadic Green functions for planar uniaxial multilayers with multiple anisotropic conductive sheets at the interfaces

Abstract

Electromagnetic Dyadic Green functions are developed for planar uniaxial multilayer media comprising multiple transversely anisotropic conductive sheets, such as graphene under magnetic bias, at the interfaces. The formulation is based on a transmission-line network analog of the stratified medium, and it employs a numerically stable reflection-transmission algorithm. Numerical examples are included to illustrate the application of the theory.
