Popis: In this paper, we introduce a novel metasurface design that supports chiral surface waves. The chiral surface waves are circularly polarized waves whose spin direction is locked to their momentum. The asymmetry in the complementary L-shaped design allows the chiral surface wave to propagate along its diagonal in which a spin-down (LCP) wave propagates forward and a spin-up (RCP) wave propagates backward. This work provides the possibility of having a laterally confined unidirectional surface wave propagation. Additionally, it can be used for polarization-based beam splitting as well as steering the beam direction.
