Abstract

Electromagnetic scattering of a Gaussian beam from a semicircular boss which protrudes above a conducting plane is investigated. The theoretical analysis for scattering is based on Kozaki´s approximation, which makes it possible to express the Gaussian beam as a product of plane wave and weight function results. The scattered fields are expressed in simple closed forms which are valid when the diameter of the boss is comparable to or less than the Gaussian beamwidth. The numerical computations are performed to find that the angular bistatic RCS (radar cross section) of the Gaussian beam is much broader in scattering pattern than the plane wave case
