Abstract

An analytical-numerical technique for the solution of the two-dimensional scattering of an electromagnetic wave by a set of circular cylinders in the presence of a plane discontinuity for the electromagnetic constants is discussed. Since the interface is only characterized by its reflection coefficient, a wide class of reflecting surfaces can be treated with the same formalism. The solution is obtainable for both the near and the far region, regardless the polarization state of the incident wave. The method exploits the possibility of representing any two-dimensional field in terms of a suitable superposition of cylindrical waves. The expansion coefficients represent the unknowns in a typical scattering problem and can be determined by imposing the boundary conditions. The presence of the interface leads to the necessity of evaluating the reflected cylindrical waves, and this is achieved starting from the Fourier spectrum of the cylindrical functions on a plane.
