Plasmonic chirality represents significant potential for novel nanooptical devices due to its association with strong chiroptical responses. Previous reports on plasmonic chirality mechanism mainly focus on phase retardation and coupling. In this paper, we propose a model similar to the chiral molecules for explaining the intrinsic plasmonic chirality mechanism of varies 3D chiral structures quantitatively based on the interplay and mixing of electric and magnetic dipole modes (directly from electromagnetic field numerical simulations), which forms mixed electric and magnetic polarizability.
等离子体手性由于与强手性响应相关联，因此在新型纳米光学器件中有很大的应用潜力。先前关于等离子体手性机制的报告主要集中在相位滞后和耦合上。在本文中，我们提出了一个类似于手性分子的模型，根据电偶极子和磁偶极子模式的相互作用和混合（直接来自电磁场数值模拟）来定量解释各种 3D 手性结构的固有等离子体手性机制，从而形成混合电和磁极化率。
