Multiple scattering by an array of finite cylindrically curved thin screens

Abstract

The electromagnetic scattering by an array of finite cylindrically curved thin screens is investigated in this paper, and the normally incident plane wave can be either TMz- or TEz-polarised. The mathematical treatment here is based on the direct integral equation technique combined with the Galerkin's procedure, and the induced currents on the curved thin screens or apertures are expanded in terms of a series of Chebyshev polynomials of the first kind. Furthermore, the far-zone field solutions to such a multiple coupling system are obtained in an analytical form, and parametric calculations are performed to show the variation of the scattered far-zone field distributions at both TMz- and TEz-polarisation incidences.
