Abstract

Analogous to surface wave formation at the interface of two semi-infinite spaces, we show a one-dimensional mode at the interface line of two semi-infinite planes that are characterized by complementary surface impedances. The proposed mode possesses singular field enhancement, tunable spatial confinement, extensive bandwidth, and robust wavevector-locked propagation, which may advance topological-like applications. Here, we specify criteria for the line wave existence and present implementations using metasurfaces and graphene that are suitable for microwave, terahertz and optical applications.
