Surrogate-Assisted Design of Checkerboard Metasurface for Broadband Radar Cross-Section Reduction
IEEE Access, 2021 Metasurfaces have been extensively exploited in stealth applications to reduce radar cross section (RCS). They rely on the manipulation of backward scattering of electromagnetic (EM) waves into various oblique angles.

Wideband radar cross‐section reduction by AMC
Electronics Letters, 2016 A new planar wideband chessboard structure is designed to reduce the radar cross‐section (RCS) of an object. This proposed chessboard configuration is composed of two different artificial magnetic conductor (AMC) tiles. One of these tiles is formed by saltire arrow unit cells, whereas the other one is formed by four E‐shaped ones.
