Abstract

In this paper we present a topological plasmonic metasurface exhibiting spin-dependent distribution in the k-space analogical to the behaviour of the K and K’ valleys in 2D materials. We intentionally break the lattice inversion-symmetry by local rotation of the lattice features and analyze the helicity dependence in the isofrequency plane. We attribute the characterisic valleytronic behavior to the local geometric Berry phase induced between the structure sublattices.
