An accurate hybrid technique for the analysis of electromagnetic scattering from an infinite periodic structure containing an impurity is presented in this paper. The hybrid formulation proposed combines a finite element method/Floquet modal expansion with the method of moments solution of a surface integral equation in the framework of an iterative approach.

Abstract
An accurate hybrid technique for the analysis of electromagnetic scattering from an infinite periodic structure containing an impurity is presented in this paper. The hybrid formulation proposed combines a finite element method/Floquet modal expansion with the method of moments solution of a surface integral equation in the framework of an iterative approach. The impurity within the infinite periodic structure can be constituted by an arbitrary material with an arbitrary shape
