On an Improved T-Matrix Approach to Study the Scalar Scattering Response of Doubly Periodic Surfaces,
Abstract
In investigating the scattering response of a periodic surface, the use of incomplete or inappropriate basis functions for representing the field(s) induced on the scattering surface has given rise to what is now called the Rayleigh Hypothesis (RH). Here the authors use normalized Fourier bases for this purpose and develop a T-matrix which completely characterizes the scalar scattering response of such a surface. The Rayleigh limits are effectively bypassed, and the obtained solutions are seen to obey unitarity as well as reciprocity constraints. They also show that the measurement of the scattered field can lead to two different interpretations of the nature of the scattering surface in inverse shape problems. (Author)
