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

摘要: In this paper, a novel set of V-dipole basis functions is introduced. These are used to approximate the induced surface current density on an infinite, plane frequency selective (FSS). The elements FSS supposed consist straight sections and bends. Two groups which present can be applied identified, namely, center connected loop-type elements. Using established spectral Galerkin method, where method moment (MoM) procedure carried out in domain, we determine reflection transmission coefficients FSS. convergence solution demonstrated both for existing bases functions. It found that double infinite Floquet sum diverges when existing, discontinuous, used, but obtained Therefore, care needs exercised, it would seem discontinuous should avoided.
