摘　　要：电磁隐身技术是提高作战武器生存能力的有效途径,对国防军事的发展具有重要意义,而减少雷达散射截面是目前最有效的电磁隐身方法。极化转化超表面在不改变其他电磁特性的基础上,能有效缩减雷达散射截面。针对极化转化超表面单元及其镜像单元在入射波照射下,两者散射波之间存在相位差的特性,设计了一种高性能单元,并采用交叉式排列,实现后向散射场的缩减。与传统棋盘式排列相比,它更能有效减缩雷达散射截面。Electromagnetic stealth technology is an effective means to improve the survivability of combat weapons,which is of great significance to the development of national defense and military,and reducing the radar cross-section is currently the most effective electromagnetic stealth method.Polarization conversion metasurfaces can effectively reduce the radar cross-section without changing other electromagnetic characteristics.In view of the phase difference between the scattered waves of polarization conversion metasurfaces element and its mirror element under the irradiation of incident waves,a high-performance element is designed,and a cross-type arrangement is adopted to reduce the backscattered field.And compared with the traditional checkerboard arrangement,it can effectively reduce the radar cross-section.
