Line waves are electromagnetic waves that propagate between planar impedance discontinuities. Being localized in the vicinity of the discontinuity, they are regarded as the one-dimensional counterpart of surface waves.
Impedance discontinuities that are necessary for line wave propagation are facilitated by two-dimensional structures such as metasurfaces and/or graphene, whose structural or electrical properties may be tuned to achieve the desired impedance.
