偏振转换双各向异性超表面的基本性质与分类

Fundamental Properties and Classification of Polarization Converting Bianisotropic Metasurfaces

Karim Achouri, Olivier J. F. Martin

摘要:

我们提供了一个详细的讨论的电磁建模和分类的极化转换双各向异性超颖表面。为此,我们首先提出了一种通用的方法来计算这种超颖表面的散射响应,这依赖于一个广义片过渡条件为基础的磁化率模型。然后,我们回顾了如何的互易性,能量守恒,旋转不变性和匹配的基本属性可能会表示在元表面的极化率和散射参数,并显示这些属性可能会影响和限制的极化效应的元表面。最后,我们将超颖表面的磁化率模型与散射粒子的结构对称性及其相关的极化效应联系起来。因此,这项工作提供了一个详细的理解超颖表面的偏振转换特性,并可能被证明是特别感兴趣的实际实施。

英文摘要:

We provide a detailed discussion on the electromagnetic modeling and classification of polarization converting bianisotropic metasurfaces. To do so, we first present a general approach to compute the scattering response of such metasurfaces, which relies on a generalized sheet transition conditions based susceptibility model. Then, we review how the fundamental properties of reciprocity, energy conservation, rotation invariance and matching may be expressed in terms of metasurface susceptibilities and scattering parameters, and show how these properties may affect and limit the polarization effects of metasurfaces. Finally, we connect together the metasurface susceptibility model to the structural symmetries of scattering particles and their associated polarization effects. This work thus provides a detailed understanding of the polarization conversion properties of metasurfaces and may prove to be of particular interest for their practical implementation.
