This study explores the possibilities of manipulating and controlling the propagation of surface waves in low-dimensional materials or metasurfaces by designing planar discontinuities in the surface impedance. Specifically, two examples are presented, namely “flat leaky waves” and “ghost line waves.” These innovative concepts have the potential to offer new avenues for controlling light at the nanoscale and could find practical applications in various fields ranging from integrated waveguides to optical sensing.
