Review of the Functions of Archimedes’ Spiral Metallic Nanostructures

Abstract

Here, we have reviewed some typical plasmonic structures based on Archimedes' spiral (AS) architectures, which can produce polarization-sensitive focusing phenomenon and generate plasmonic vortices (PVs) carrying controllable orbital angular momentum (OAM) because of the relation between the incident polarized states and the chiralities of the spiral… (More)
