摘要:

依靠纳米结构的局部取向,Pancharatnam-Berry超颖表面目前正在实现新一代偏振敏感光学器件。一个系统的介观描述的拓扑超颖表面的发展,提供了一个更深入的理解的物理机制,导致偏振相关的打破平移对称性与传播相位效应。这些理论结果,以及干涉实验,有助于发展一个坚实的理论框架,任意偏振相关的超颖表面。

英文摘要:

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 theoretical framework for arbitrary polarization-dependent metasurfaces.
