Numerical and Experimental Study of Curved and Planar Frequency SelectiveSurfaces with Arbitrary Illumination

摘要

A frequency selective surface (FSS) composed of apertures in a metallic sheet isknown as the inductive FSS. The infinite inductive FSS theory is derived and the aperture fields are solved by a spectral domain formulation with method of moments solution. Both full domain and subsectional basis functions are studied. A locally planar technique (LPT) is used to determine the forward scattered field from a generally shaped inductive FSS with arbitrary illumination.
