Abstract

Surface plasmon polaritons (SPPs) promise versatile potential applications in many aspects and thus have been a subject of enormous interest. However, in the terahertz regime, due to perfect conductivity of most metals, it is hard to realize a strong confinement of SPPs although a propagation loss could be sufficiently low. Here we introduce the recent work from terahertz surface waves to spoof SPPs based on metasurfaces.
