提出了一种用于雷达散射截面（RCS）减缩的超表面。该表面由相同类型的具有不同几何尺寸的超材料单元组成，导致在平面波入射下的各种反射相位。通过仔细选择相位分布，使反射波产生扩散，使表面的散射能量向各个方向重新分布，从而可用作超低RCS金属目标的涂层。仿真和实验结果都验证了该方法的有效性。
A metasurface for Radar Cross Section (RCS) reduction is proposed. The surface is composed of the same type of metamaterial units with different geometric dimensions, leading to various reflection phases under the incidence of plane waves. By carefully choosing the phase distributions, diffusion will be produced for the reflected waves which may redistribute the scattering energy from the surface toward all the directions, and hence it can be applied as the coating of metallic targets with ultra-low RCS. Both the simulated and experimental results have validated the proposed method.
