Electromagnetic scattering from a stack of two one-dimensional rough surfaces separating homogeneous media is modeled with rigorous integral formulation solved by the method moments. We present an efficient numerical for computing field scattered such layers, in reflection as well transmission. call this propagation-inside-layer expansion (PILE) due to its straightforward physical interpretation. To our knowledge, it first able handle problems configuration huge number unknowns. study convergence versus coupling condition and validate comparison results literature.
