Unidirectional propagation can be excited via a chiral point source placed near the junction. The equivalent impedances of metasurfaces are extracted to establish a simplified semianalytical model to study their spin-momentum locking properties. It is found that broadband LWs can be supported by metasurfaces with varied surface wave momentum, and the dispersion of LWs can be tailored by tuning either their capacitive or inductive properties. We explore intrinsic properties of LWs including dispersion, confinement, and spin-momentum locking. ![]() Here, we introduce a compact dual-impedance metasurface platform to explore the properties of LWs. Such attractive characteristics show potential applications for robust waveguides. These edge modes are tightly confined to the interface and can propagate along arbitrary one-dimensional paths with high efficiency. ![]() Line waves (LWs) are special electromagnetic modes supported on junctions of different metasurfaces that enforce a duality condition, such as capacitive and inductive metasurfaces.
