Generally Incident Fresnel Coefficients for Simple to Biaxial Media Interfaces

Generalized closed form expressions of the Fresnel coefficients for an arbitrarily incident plane wave upon a simple to biaxial media interface is introduced. The analysis enforces boundary conditions through eigenwave expansions of both the simple media and anisotropic permittivity and permeability biaxial media. This generalized eigenwave approach results in explicit formulations accounting for the co- and cross-polarized scattering components from the simple to biaxial media interface. The solutions in this paper can be used to analyze scattering phenomena of general biaxial media as well as address theoretical scattering parameter formulations for material measurement techniques.
