Generalized method for electromagnetic scattering by two-dimensional periodic discrete composites using lattice sums

Abstract

A very efficient and accurate method to characterize the electromagnetic scattering from multilayered periodic arrays of two-dimensional composite cylindrical objects is presented, using the lattice sums formula and the aggregate T-matrix for cylindrical structures. The method is quite general and applies to various configurations of two-dimensional periodic arrays. The unit cell of the array call contain two or more cylinders, which may be dielectric, conductor, gyrotropic medium, or their mixture with different sizes.
