Scattering from frequency selective surfaces: An efficient set of V-dipole basis functions

Poulsen, Sören LU (2000) In Technical Report LUTEDX/(TEAT-7083)/1-17/(2000) TEAT-7083.
Abstract
In this paper a novel set of V-dipole basis functions is introduced. These

basis functions are used to approximate the induced surface current density

on an infinite, plane frequency selective surface (FSS). The elements of the

FSS are supposed to consist of straight sections and bends. Two groups of

elements which the present V-dipole basis functions can be applied to are

identified, namely the center connected elements and the loop type elements.

Using the established spectral Galerkin method, where the method of moment

(MoM) procedure is carried out in the spectral domain, we determine the

reflection and transmission coefficients of the FSS. The convergence of... (More)
In this paper a novel set of V-dipole basis functions is introduced. These

FSS are supposed to consist of straight sections and bends. Two groups of

Using the established spectral Galerkin method, where the method of moment

(MoM) procedure is carried out in the spectral domain, we determine the

reflection and transmission coefficients of the FSS. The convergence of the

solution is demonstrated both for existing bases and the present V-dipole

basis functions. It is found that the double infinite Floquet sum diverges

when existing, discontinuous, basis functions are used, but that convergence is

obtained for the present basis functions. Therefore, care needs to be exercised

and it would seem discontinuous bases should be avoided. (Less)
