Electromagnetic (EM) waves have been widely applied in wireless communications, radar detection, navigation, and target recognition. Radiation and scattering are two common behaviors in the EM community, but it remains a long‐standing challenge to control them in a dynamical way, especially using a single, low‐cost, and compact hardware. Here, a promising solution is proposed by combining a programmable metasurface with a radiation array, which can manipulate the scattering properties, digitally and in real‐time, and exhibit different radiation modes simultaneously. More advantageous over previous investigations with the fixed radiation‐scattering performance, a field‐programmable gate array is introduced to extend, realize, and verify the multiple functions of the meta‐microstructure (MMS). As a proof‐of‐concept, multiple functions, including polarization conversion, scattering beam manipulation, diffusion scattering, radar cross‐section reduction, EM waves radiation, and vortex beam generation, have been adequately demonstrated by the MMS prototype.

辐射阵列散射特性的可编程控件

电磁波（EM）已广泛应用于无线通信，雷达检测，导航和目标识别中。辐射和散射是EM社区中的两种常见行为，但是以动态方式控制它们（尤其是使用单个，低成本且紧凑的硬件）仍然是一项长期的挑战。在此，通过将可编程的超颖表面与辐射阵列相结合，提出了一种有前途的解决方案，该阵列可以数字和实时地控制散射特性，并同时显示不同的辐射模式。与以前的研究相比，在固定辐射散射性能方面更具优势，引入了现场可编程门阵列，以扩展，实现和验证亚微结构（MMS）的多种功能。作为概念验证，多种功能
