Modal method for scattering by arbitrarily shaped multivalued surfaces

Mostrar todas las versiones(2)

We present a modal method to calculate the electromagnetic fields scattered by a perfectly conducting surface with a finite number of grooves described by non-single-valued functions. The surface can be illuminated by s-or p-polarized Gaussian beams with propagation directions perpendicular to the g...
