Checkerboard Plasma Electromagnetic Surface for Wideband and Wide-Angle Bistatic Radar Cross Section Reduction

Bistatic radar cross section (RCS) of a metal plate is reduced by an improved checkerboard surface cover. Plasma and metallic frequency selective surfaces are studied analytically to achieve a proper reflection phase interval. More than 140° phase of the reflected wave is obtained as a promising method to reduce the returned wave in the way of incident wave or any other directions. Hence, a checkerboard surface is designed using the concrete numerical and analytical solutions for backscattering cancellation. Monostatic and bistatic cross sections of metal screens are reduced with the designed plasma electromagnetic surface coat. The amount of bistatic (RCS) is analyzed with a valuable equation. Wide frequency band, vast incident wave angles, and different wave polarizations are achieved for the bistatic analysis. Incorporation of plasma dielectric with metal surface, reconfigurable design, and analysis of the bistatic backscattering of the structure are the promising achievements.
