编码声元表面可以将简单的逻辑位联合收割机组合以获得波控制中的复杂功能。声学逻辑比特可以实现精确的p的相位差和所发射波的幅度的完美匹配。通过对编码序列进行编程，实现了具有各种功能的声学超表面，包括产生特殊的天线方向图和波聚焦。
Coding acoustic metasurfaces can combine simple logical bits to acquire sophisticated functions in wave control. The acoustic logical bits can achieve a phase difference of exactly p and a perfect match of the amplitudes for the transmitted waves. By programming the coding sequences, acoustic metasurfaces with various functions, including creating peculiar antenna patterns and waves focusing, have been demonstrated.
