Abstract
In this work we explore photonic topological edge states arising in dielectric metasurface based on a deformed honeycomb lattice. We demonstrate numerically the effect of pseudo-spin locking of the edge states and verify its existence experimentally in microwave frequency range. Our findings thus demonstrate that open non-Hermitian metasurface can support the topological edge modes despite the radiative losses.
