介绍了一种具有低雷达散射截面(RCS)特性的超曲面的设计。通过采用三种不同构型的人工磁导体(AMC)单胞，实现了亚表面的低散射。首次设计了两个有效相位差为180±37°的AMC单元格，用于分析5.9~12.2 GHz宽带范围内的异相反射。然后，将单元放置在棋盘式构型、新构造的旋转矩形构型和优化构型中，研究和比较RCS的降低性能。与相同尺寸的金属板相比，不同构型的金属表面的RCS都有明显的降低。然而，优化后的变形表面的相对带宽大于棋盘状和旋转矩形构型。为了验证模拟的结果，进一步制作了具有优化配置的亚表面，以测量RCS缩减带宽。测量结果与模拟结果吻合较好。因此，对于需要较低RCS的应用来说，建议的变形曲面是一个很好的选择。
The design of a metasurface with low radar cross section (RCS) property is presented in this paper. The low scattering of the metasurface is achieved by applying the artificial magnetic conductor (AMC) unit cells in three different configurations. Two different AMC unit cells with an effective phase difference of 180 ± 37° are first designed to analyze the out of phase reflection in a wideband frequency range from 5.9 to 12.2 GHz. Then, the unit cells are placed in a chessboard-like configuration, newly constructed rotated rectangular-shaped configuration, and optimized configuration to study and compare the RCS reduction performance. All designs of the metasurface with different configurations show obvious RCS reduction as compared with the metallic plate of the same size. However, the relative bandwidth of the optimized metasurface is larger than the chessboard-like configuration and rotated rectangular-shaped configuration. To certify the results of the simulations, the metasurface with the optimized configuration is fabricated further to measure the RCS reduction bandwidth. The measured results are in good accordance with the simulated results. Therefore, the proposed metasurface can be a good option for applications where low RCS is desirable.
