摘要

提出了一种新的超级单体概念来控制超表面反射器的振幅和相位，独立于两个正交偏振，并进行了数值验证。超级单体的概念是基于一个基本单元，它只在一个线性极化上工作，当空间旋转90°时，可以用来响应另一个正交极化。通过空间组合单元电池及其空间旋转版本，形成了一个超级电池，它可以赋予每个偏振所需的反射幅度/相位而不影响另一个。

Metasurface Reflector with Independent Polarizations Control using a Supercell Concept

A novel supercell concept is proposed to control the amplitude and phase of a metasurface reflector, independently for the two orthogonal polarizations, and is numerically demonstrated. The supercell concept is based on a fundamental unit cell that operates on one linear polarization only, which when spatially rotated by 90°, can be used to respond to the other orthogonal polarization. By spatially combining the unit cell and its spatially rotated version, a super cell is formed which can impart a desired reflection amplitude/phase to each of the polarizations without affecting the other.
