A Green function approach to surface optics in anisotropic media

A formalism based on dyadic Green functions is applied to the reflection and transmission of fields generated in the presence of anisotropic media. Our approach is general and treats the fields immediately in terms of s- and p-polarized components. Hence, the Fresnel reflection and transmission coefficients appear naturally in our expressions. The asymptotic far-field expansions of the dyadic Green functions are easily obtained, and numerical calculations in experimental geometries are straightforward.
