Reflection From Stratified Media Backed by a Perfect Electromagnetic Conductor (PEMC)

Perfect electromagnetic conducting (PEMC) boundary is a generalization of both PEC and PMC boundaries, creating nonreciprocal reflection which could be cross-polarized with respect to the incident wave. In this communication, reflection from a stratified medium, backed by a PEMC boundary due to an oblique incident plane wave is calculated analytically. In general, the medium is considered as N layers of frequency dispersive bianisotropic media. Applying the PEMC boundary condition, the reflection dyadic is computed using the notion of propagators and wave-splitting technique. The method is validated through deriving the reflection dyadics of a plane wave from 1) PEC-backed stratified medium and 2) a PEMC-free space interface whose analytical expressions exist. Furthermore, few numerical examples illustrating the method as well as its applications are provided.
