摘要

提出了一种新型的由六边形超材料单元格构成的蜂窝状透射阵列透镜(TAL)，用于产生会聚轨道角动量光束。与最常见的方晶格阵列相比，蜂窝TAL可以提供更宽的工作频带，更大的相移范围和稳定的频率响应，作为入射电磁波的角度和偏振的函数。仿真结果验证了该设计的有效性。

A Honeycomb Transmit-Array Lens with Hexagonal Lattice for Generation of OAM Waves

A novel honeycomb transmit-array lens (TAL) constructed from hexagonal metamaterial unit cell is presented for generating the convergent orbital angular momentum (OAM) beams. Compared with the most common square-lattice arrays, the proposed honeycomb TAL can provide a wider operating band, a larger phase-shift range and stable frequency responses as the function of angle and polarization of the incident EM wave. The simulated results verify the effectiveness of the proposed design.
