Broadband RCS Reduction Using Circular Sector Structure

In this paper, a new metasurface structure is designed to reduce radar cross section (RCS). order the (RCS), designed. The unit adopts polarization conversion structure, which composed of asymmetric double arrow-shaped metal and etched on dielectric substrate back plate. This (PCM) consists it backed with metallic It can realize converting linear polarized waves orthogonal ones in broadband from 18.1 GHz 32.7 efficiently. According further development triangle chessboard layout, we also several circular fan-shaped configurations, RCS reduction wider -10 dB bandwidth compared configuration. Finally, an optimized 8-lobed sector configuration PCM selected for processing testing. greater than 10 wide ranging 13.7 27.5 GHz, equal-sized metallic-backed experimental results basically agree simulation ones. proposed has broad application prospects such as phased array antenna technology, electromagnetic stealth absorption technology.
