Computation of scattering from dielectric rough surfaces via the forward-backward method

The iterative forward-backward (FB) method is an efficient technique for numerical evaluation of scattering from perfectly conducting 1-D rough surfaces. In this paper, the FB method is generalised to analyse scattering from dielectric 1-D rough surfaces. Effectiveness of the method is assessed by comparing obtained scattering results with the "exact" ones, computed by direct use of the method of moments (MoM).
