Abstract Relying on the local orientation of nanostructures, Pancharatnam–Berry metasurfaces are currently enabling a new generation of polarization-sensitive optical devices. A systematical mesoscopic description of topological metasurfaces is developed, providing a deeper understanding of the physical mechanisms leading to the polarization-dependent breaking of translational symmetry in contrast with propagation phase effects. These theoretical results, along with interferometric experiments contribute to the development of a solid analytical framework for arbitrary polarization-dependent metasurfaces.

使用介观电动力学揭示 Pancharatnam-Berry 超表面的拓扑相

摘要依赖于纳米结构的局部取向，Pancharatnam-Berry 超表面目前正在支持新一代偏振敏感光学器件。开发了拓扑超表面的系统细观描述，提供了对导致平移对称性与极化相关的破坏与传播相位效应形成对比的物理机制的更深入的理解。这些理论结果以及干涉实验有助于为任意偏振相关的超表面开发可靠的分析框架。
