Visible-broadband Localized Vector Vortex Beam Generator with a Multi-structure-composited Meta-surface
We demonstrate a vortex beam generator meta-surface that consists of silver structures and graphene layers. The miniature material is just a few microns in size and the working part is only a few hundred nanometers thick. With the incidence of the linearly polarized beam, the meta-surface generates...
