论文摘要
在使用跨境的基本电磁特性后，我们构建了一个平台，从典型的实验测量中对相互的双性异性偏移进行分类，并确定各向同性，各向异性，双性异性（手性）和双性异性（bianisotropic（手态）和bianisotropic（手力）（所谓的欧米茄）。我们提供实验指南来通过测量宏观散射参数，即用线性和/或圆形极化来识别宏观散射参数，即反射和传输系数。我们明确地提供了一个食谱，说明跨表面属性可以并且无法通过选定的极化，反射和传输属性来推断。我们还阐明了基于近期文献中提出的圆二色性测量值的各向异性与手性跨膜分类的共同混乱。
Upon using fundamental electromagnetic properties of metasurfaces we build a platform to classify reciprocal bianisotropic metasurfaces from typical experimental measurements and determine isotropic, anisotropic, bi-isotropic (chiral), and bianisotropic (so-called omega) properties. We provide experimental guidelines to identify each class by measuring macroscopic scattering parameters, i.e., reflection and transmission coefficients upon plane wave illumination with linear and/or circular polarization. We explicitly provide a recipe of what metasurface properties can and cannot be inferred by means of chosen polarization, reflection, and transmission properties. We also clarify common confusions in the classification of anisotropic versus chiral metasurfaces based on circular dichroism measurements presented in the recent literature.
