Abstract :
An iterative technique is described for solving for the current and field distributions in a structure composed of a periodic array of sheet conductors, deposited on a dielectric layered substrate, whether or not backed by a conductor. The incident field must be a plane wave but can be oblique. The periods array is taken into account by use of a Floquet mode field formalism, and an iterative method has been chosen that permits a numerical solution on personal computers by avoiding matrix inversions
