Abstract

We consider here the scattering of a plane wave at a flat boundary characterized by a coordinate-dependent surface impedance that varies periodically only over a finite region. This surface impedance represents a wide class of scattering structures that includes finite-diffraction gratings. Numerical results are obtained to show the adequacy of this canonical model.
