Creates variables to mimic specular reflection by a (flat) surface where surface_rv_rh is specified.

This method assumes that the reflection at vertical and horizontal polarisation differs. As power reflection coefficients are provided there is no information at hand on phase shifts between polarisations, and they are simply assumed to be zero. These assumptions result in that surface_emission is set to zero for positions corresponding to U and V, and that all diagonal elementsof surface_rmatrix are equal (the mean of rv and rh). Further, all off-diagonal elements of surface_rmatrix are all zero except for (0,1) and (1,0).
