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

This method assumes that the reflection at vertical and horizontal polarisation is identical. This assumption includes that there is no phase shift between polarisations. These assumptions result in that surface_emission is set to zero for positions corresponding to Q, U and V, and that surface_rmatrix becomes a diagonal matrix (with all elements on the diagonal equal to the specified reflectivity).
