双各向异性开口环谐振器超薄膜中的Brewster效应
Brewster effect in metafilms composed of bi-anisotropic split-ring resonators
摘要：
布鲁斯特效应被扩展到单层超薄膜。与体相介质相比，超薄膜中的布鲁斯特效应可以通过定制超原子分布的辐射图案而不是有效介质参数来实现。基于该理论设计了一种由双各向异性开口环谐振器组成的超薄膜，并对其特性进行了数值分析。模拟表明，存在一个条件，反射波的偏振变得独立于入射偏振在一个特定的入射角。
英文摘要：
The Brewster effect is extended to single-layer metafilms. In contrast to bulk media, the Brewster effect in metafilms can be realized by tailoring the radiation pattern of a distribution of meta-atoms rather than the effective medium parameters. A metafilm composed of bi-anisotropic split-ring resonators is designed based on the theory, and its characteristics are numerically analyzed. The simulation demonstrates that there exists a condition for which the polarization of the reflected wave becomes independent of the incident polarization at a particular angle of incidence.
