Plane Wave Scattering by Two PEC Zero-Thickness Disks Placed above Half-Plane

Abstract

Plane wave scattering by the system, which consists of the perfectly-electric conducting (PEC) zero thickness half-plane and two PEC zero-thickness circular disks is considered. We study only the case when the disks are placed on the one side of the half-plane. The meshless full-wave code is based on the operator method. The scattered field is expressed in terms of the superposition of the plane waves with the use of the Fourier integrals with unknown amplitudes. The operator equations for these amplitudes are reduced to the integral equations. Since the scattering operators of the half-plane have singularities, the regularization procedure is performed. The scattered field can be represented as a superposition of the plane wave, cylindrical and spherical waves. The far field of the spherical waves and the total near field is studied.
