论文摘要
我们概念化了仅包含三个薄带网格的三阵列可伸缩元面积，并在数值中证明了它们在中红外光谱方案中的特性，用于可切换极化操纵和相关的不对称二极管传输（AT）。几个或全部的网格被视为由vo $ _2 $（一种变化材料）制成。对于每个提出的元表面，存在两个有效的结构，因此存在两个不同的功能，与VO $ _2 $的金属和绝缘阶段相对应。依赖于vo $ _2 $相位的功能切换的方案显示出很大程度上取决于将vo $ _2 $合并到metasurface的方式。极化操作的可切换带高达40 THz宽。当Fabry- Perot（Anti-）共振发挥作用时，可以调制AT乐队。
We conceptualized three-array scalable metasurfaces comprising only three thin strip grids and numerically demonstrated their characteristics in the mid-infrared spectral regime for switchable polarization manipulation and related asymmetric diodelike transmission (AT). A few or all of the grids were taken to be made of VO$_2$, a phase-change material. For each proposed metasurface, two effective structures and, therefore, two different functionalities exist, corresponding to the metallic and insulating phases of VO$_2$. The achieved scenarios of functionality switching that depend on the VO$_2$ phase are shown to significantly depend in the way in which VO$_2$ is incorporated to the metasurface. Switchable bands of polarization manipulation are up to 40 THz wide. The AT band can be modulated when Fabry--Perot (anti-)resonances come into play.
