Full Wave Analysis of Finite Uniform Metallic Grid FSS under Oblique Incidence Using Scale Changing Technique

摘要

This paper presents an overview on Scale Changing Technique (SCT) global electromagnetic simulations used in the case of finite size Grid FSS consisting of rectangular perforations on a metallic screen. The grid structure, illuminated by an oblique incident plane wave, is analyzed using Scale Changing Technique which is based on the partition of the grid-plane into planar sub-domains defined at various scale-levels. Electromagnetic interaction between subsequent scales is modeled by mutually independent Scale Changing Networks and finally the complete structure can simply be represented by a cascade of these scale-changing networks. Simulation results of radiation diagram are shown in order to demonstrate the validity of the approach.
