摘要

本文设计了由7个不同几何形状的弧形交叉金属-介质-金属单元组成的相位梯度超表面，实现了3GHz波段的异常反射，x极化波和y极化波的反射效率均达到99%。对近电场分布的模拟结果表明，异常反射角与理论分析非常吻合。这种超表面可以很容易地扩展到其他频段，并在光通信中找到潜在的应用。

Realization of high-efficiency anomalous reflection using phase gradient metasurface at UHF

In this paper, a phase-gradient metasurface which consists of 7 arcuate cross-shaped metal-medium-metal units with different geometries is designed to realize anomalous reflection at 3GHz with 99% reflection efficiency of both x-polarized and y-polarized waves. The simulation results on near electric field distributions show excellent agreement of the anomalous reflection angle with theoretical analysis. This metasurface can be easily scaled to other frequency bands and find potential applications in optical communications.
