Radar-Cross-Section Reduction Using Polarization Conversion Metasurface
A polarization converter metamaterial surface (PCM) surface is designed for radar-cross-section reduction (RCSR) applications, through this paper. The presented PCM unit-cell composed of crescent shaped metallic patch. It introduces polarization conversion ratio (PCR) of 0.9 in the frequency-band from 8.2 GHz to 11.5 GHz. Different PCM surfaces arrangements uniform, triangle, and square structures are constructed and studied for more RCSR performance. The PCM square arrangement surface involves the rotation of the crescent unit cell with 90, 180 and 270 degrees to enhance the scattered waves cancellation and hence produce more RCSR. It introduces the optimum RCSR of 22.5 dB at 8.7 GHz for normal incident wave. The paper investigates the RCSR from different planar and conformal metallic surfaces loaded with PCM square arrangement. Different radii of surface curvature are investigated.
