Scattering by a Truncated Periodic Array.

Abstract

The scattering characteristics of a doubly periodic array of metallic patches is investigated in this paper from the point of view of determining the effect of truncating such a screen. The induced surface current on each patch of the array as well as the scattered far-field pattern of the truncated array are computed using the spectral-Galerkin method. The usefulness of the results for the truncated screen problem for the design of frequency selective surfaces (FSS) is discussed. Keywords include: scattering, frequency selective surface (FSS), truncation, and periodic array.
