Abstract
Artificially hard and soft surfaces, which are often used for their properties in radiating systems, are characterized by means of a hybrid technique which utilizes the finite element method (FEM) and an expansion of the electromagnetic field in terms of Floquet's modes. This method is very efficient and allows the analysis of scattering from arbitrary periodic structures. No further difficulties arise in the formulation of the problem when the complexity of the structure is increased
