Spin-momentum locking is a phenomenon recently explored in electromagnetic waves that possess an evanescent tail which is accompanied by a transverse spin due to out-of-plane field rotation. In this paper, we introduce a novel metasurface design that supports chiral surface waves. The chiral surface waves are circularly polarized waves that possess two transverse spins, one due to out-of-plane field rotation which is intrinsic to any surface wave, and the other is due to in-plane field rotation which is imposed by the design. Both spins follow the spin-momentum locking resulting in unidirectional wave propagation. This work provides an additional degree of freedom to control the spin-orbit interaction of electromagnetic waves. |
