Fast analysis of FSS radome for antenna RCS reduction

This work presents a method for the analysis of large frequency selective radomes relying on the combination of a high frequency approach, based on a locally planar approximation, and the PRM method for an efficient characterization of the planar selective structure. The proposed approach combines efficiency and conceptual simplicity with a reasonable accuracy, thus providing a tool for a fast analysis of antennas enclosed by large arbitrarily shaped frequency selective radomes
