摘要

分析和设计了一种采用新型双线偏振反射元件的超表面，可产生两种OAM模式。该元件由一个交叉贴片和衬底两侧的四条相位延迟线组成，通过金属过孔连接以最小化单元。仿真结果表明，两种模式在观测平面上的相位和振幅均满足要求。该方法可以进一步促进OAM复用的应用。

Reflection-Type Metasurface for Generating Two Orbital Angular Momentum Modes Based on Orthogonal Polarization

A metasurface with novel dual linear polarization reflective element generates two OAM modes is analyzed and designed. The element consists of a cross patch and four phase delay lines on both sides of the substrate, connected by metal vias for cell minimization. The simulation results show that the phase and amplitude of two modes on the observation plane meet the requirements. The proposed method could further promote the application of OAM multiplexing.
