论文摘要
我们提供了有关转换双异构性元面的极化转换的电磁建模和分类的详细讨论。为此,我们首先提出了一种一般方法来计算此类跨度的散射响应,该方法依赖于基于广义的板过渡条件模型。然后,我们回顾如何以跨表面的敏感性和散射参数来表达互惠,节能,旋转不变性和匹配的基本特性,并显示这些特性如何影响和限制跨境的极化影响。最后,我们将元表敏感性模型与散射颗粒的结构对称性及其相关的极化效应联系在一起。因此,这项工作详细了解了元时间的两极分化转换属性,并可能对其实际实施特别感兴趣。
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.
