Diffraction of an electromagnetic plane wave by a metallic sheet

Abstract

A new generalized technique is developed for the solution of the problem of the diffraction of a plane-wave incident at an oblique angle on an imperfectly conducting half plane. It is shown that the solution may be deduced directly from the known scalar solutions for the half plane. The case when the incident wave is E-polarized is considered in detail. The method of solution is applicable to the case of an H-polarized wave and also to the case when the diffracting structure consists of a finite number of parallel sheets of conducting material. The solution for an arbitrary incident wave may be obtained by superposition of the plane wave solutions.
