Programmable metasurface enables controlling electromagnetic (EM) waves in real time. By programming the states of active device embedded in metasurface element, the EM properties of the digital metasurface can be changed quickly without redesigning their structures. However, large numbers of long-distance wires are required to connect the programmable metasurface to provide the coded signals from field programmable gate array (FPGA) when controlling the metasurface at a long distance, which is complicated and inconvenient. Here, we propose an infrared-controlled programmable metasurface that can be programmed remotely. The infrared transceiver is able to switch the coding sequences stored in the FPGA controller, thus controlling the voltage on the varactors integrated in the metasurface. Experiment is performed at microwave frequencies, and the measured results verify that the scattering beams of the metasurface sample can be changed remotely by using infrared ray. The proposed infrared-controlled programmable metasurface opens up avenues for constructing a new class of remotely-tuning dynamic metasurfaces.

可编程超颖表面能够实时控制电磁（EM）波。通过编程嵌入超表面元素中的有源设备的状态，可以快速更改数字超表面的EM属性，而无需重新设计其结构。然而，当在远距离控制超颖表面时，需要大量的长距离导线来连接可编程超颖表面以提供来自现场可编程门阵列（FPGA）的编码信号，这是复杂且不便的。在这里，我们提出了可以远程编程的红外控制的可编程超颖表面。红外收发器能够切换存储在FPGA控制器中的编码序列，从而控制集成在超表面上的变容二极管上的电压。实验是在微波频率下进行的，实测结果表明，利用红外光谱可以远程改变超表面样品的散射光束。所提出的红外控制可编程超颖表面为构造新型的远程调谐动态超颖表面开辟了道路。
