Abstract:
A real diffraction grating is simulated by a plane boundary with a coordinate-dependent surface impedance. This surface impedance is constructed as the sum of two complex functions: a perfectly periodic function representing a grating without defects, plus a randomly varying, spatially localized function that represents the microroughness or defects of a real grating. This alternative scattering problem is solved in a rigorous electromagnetic manner for two polarizations of the incident field. Our results show that when the magnetic field is parallel to the grooves the scattered light pattern exhibits intensity maxima. The behaviour of these peaks reproduces that reported for the diffuse light bands observed in the spectrum of a real grating. © 1989 Taylor & Francis Ltd.
