description The invention discloses a broadband radar cross-sectional area reduction metasurface with reflection and scattering characteristics, which comprises a plurality of square structure units arranged in a set mode, each square structure unit comprises a bottom-layer metal plate unit, an upper-layer special-shaped metal belt unit and a dielectric substrate unit arranged between the bottom-layer metal plate unit and the upper-layer special-shaped metal belt unit; according to the invention, two special functions, namely reflection and scattering of incident electromagnetic waves, can be integrated in a relatively wide frequency band, so that the functions of specular reflection and RCS reduction are realized. 本发明公开了一种具有反射和散射特性的宽带雷达散射截面积缩减超表面，包括若干个呈设定方式排布的方形结构单元，每个方形结构单元包括底层金属板单元、上层异形金属带单元和设置在底层金属板单元与上层异形金属带单元之间的介质基底单元；本发明能够在较宽的频带内集成两种特殊的功能，即对入射电磁波的反射和散射，从而实现镜面反射和RCS缩减的功能。
