Generalized Wait-Hill Formulation Analysis of Lumpedelement Periodically-Loaded Orthogonal Wire Grid Generic Frequency Selective Surfaces

By combining the work of J. R. Wait on a periodically loaded vertical wire grid and the work of D. A. Hill and J. R. Wait on a wire mesh, a novel generalized formulation, the Wait-Hill formulation, is obtained for the analysis of lumped-element periodically-loaded orthogonal wire grid generic frequency selective surfaces. The Wait-Hill formulation is simple and not restricted by the miniaturization assumption of current approximate simple methods for the analysis of loaded and unloaded wire grids. The results of the Wait-Hill formulation are shown to agree well with those of a commercial software.
