PLANE-WAVE SCATTERING BY A PERFECTLY CONDUCTING CIRCULAR-CYLINDER NEAR A PLANE SURFACE - CYLINDRICAL-WAVE APPROACH

A new method for the analysis of the diffraction of a plane wave impin ging on a perfectly conducting circular cylinder in front of a general ly reflecting surface is presented. The surface is characterized by it s complex reflection coefficient, enabling us to treat a wide class of reflecting surfaces. The presence of the surface is taken into accoun t by means of a suitable expansion of the reflected field in terms of cylindrical functions. The method gives the solution of the scattering problem in both the near and the far field regardless of the polariza tion state of the incident field. Numerical examples for dielectric in terfaces are presented, and comparisons are made with results presente d in the literature. (C) 1996 Optical Society of America
