为实现60 GHz轨道角动量(OAM)光束的产生和会聚，设计了一种基于多层移相面的平板，提供透镜和螺旋相位板的组合。该设计由一系列相移单元格组成，用于控制出射相位并形成用于光束聚焦的平透镜。仿真和实验结果表明，可以实现发散角较小的OAM波束。
A multilayer phase-shifting-surface-based flat plate is designed to offer a combination of lens and spiral phase plate (SPP) for orbital angular momentum (OAM) beam generation and convergence at 60 GHz. The proposed design consists of a series of phase-shift unit cells to control the emergent phase and form a flat lens for the purpose of beam focusing. The results of simulation and experiment verify that the OAM beam with small divergence angle can be achieved.
