Abstract :
We have modeled a two-dimensional periodic structure by a two-dimensional impedance surface. The scattering of waves by such an impedance surface is rigorously formulated as a three-dimensional boundary-value problem, including the coupling between the TE and TM polarized waves. Numerical examples are given to illustrate physical phenomena associated with the structure.
