Query: Revealing topological phase in Pancharatnam-Berry metasurfaces using
  mesoscopic electrodynamics   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.
