摘要: In this paper we designed and fabricated a metasurface working as radar cross section (RCS) reducer over an ultra wide band of frequency from 3.8 to 10.7 GHz. The is chessboard-like surface made alternating tiles, with each tile composed identical unit cells. We develop novel, simple, highly robust fully automated approach for designing the First, topology optimization algorithm used engineer shape two area cell pixelated. A particle swarm applied wherein pixel corresponds bit having binary value 1 or 0 indicating metallization no metallization. With objective reducing RCS specified range, then linked full wave three-dimensional electromagnetic simulator. To validate design procedure, was designed, experimentally tested showing significantly enhanced performance than previous works. Additionally, angular analysis also presented good stability wide-angle behavior reducer. procedure has range applications can be easily extended surfaces antennas, energy harvesters, noise mitigation in electronic circuit boards amongst others.
