We assume that the diffraction matrices of the layers (or even slabs) composing the surface have been obtained by any of the methods of Chap. 5–8. The Renormalized Forward Scattering (RFS) perturbation method [15] follows the principle that transmission through any layer should not be described by unperturbed plane waves, but rather by plane waves modified for forward scattering through that layer together with all other plane waves transmitted with various scattering angles. It is the reflection by any layer that is considered to be weak and the perturbation is therefore based on an expansion of the total reflectivity of the surface in terms of the number of reflections: the lowest order contains all paths that have been reflected only once, but transmitted any number of times; the next order contains only triple-reflection paths (odd numbers of reflections are needed to bring electrons back out of the surface), and so on.
