Abstract

In this paper, the scattering from two homogeneous scatterers embedded in a homogeneous medium is investigated by using an efficient rigorous method based on the method of moments, published by N. Dechamps and recently extended by G. Kubicke, and referred as to E-PILE (extended propagation-inside-layer-expansion). This method is applied for a circular cylinder near (above or below) a one-dimensional (1-D) rough surface, and for a stack of two 1-D rough surfaces separating homogeneous media. In addition, to decrease its complexity, the forward-backward spectral acceleration of Chou and Johnson is applied to calculate the local interactions on the rough surface(s).
