Radar Cross Section Reduction Using Electromagnetic Band-Gap Checkerboard Surfaces


Abstract Electromagnetic band-gap (EBG) structures have noteworthy electromagnetic characteristics that include their phase variations with frequency. When combining perfect electric conductor (PEC) and EBG structures on the same ground plane, the scattering fields of the ground plane are altered because of the scattering properties of EBG structures. The scattering fields are cancelled along the principal planes because PEC and EBG structures are anti-phase at the resonant frequency. To make the scattered fields symmetrical under plane wave incidence, a square checkerboard surface is designed to form constructive and destructive interference scattering patterns to reduce the intensity of the scattered fields toward the observer; thus reducing the r...
