Workspace Method surfaceFlatRefractiveIndex
Description
Creates variables to mimic specular reflection by a (flat) surface where the refracive index is specified. The dielectric properties of the surface are described by complex_n. The Fresnel eqiuations are used to calculate amplitude reflection coefficients. The method can thus result in that the reflection properties differ between frequencies and polarizations. Local thermodynamic equilibrium is assumed, which corresponds to that the reflection and emission coefficients add up to 1.
