Numerical derivation of diffraction coefficients using a method of moments with incorporated absorbing boundaries

Abstract
In this letter, a method is presented to numerically derive uniform theory of diffraction-like diffraction coefficients for canonical structures. To deal with the semi-infinite nature of these nonstandard structures, the coordinate stretching formulation of a perfectly matched layer is integrated into a method-of-moments-based boundary integral equation solver. The method is validated for diffraction of a plane wave at a perfectly electric conducting (PEC) slab and further, by way of example, applied to a pencil-shaped PEC and a brick wall slab.
