    "abstract": "In this letter we show how the dispersion relation of surface plasmon\npolaritons (SPPs) propagating along a perfectly conducting wire can be tailored\nby corrugating its surface with a periodic array of radial grooves. In this\nway, highly localized SPPs can be sustained in the terahertz region of the\nelectromagnetic spectrum. Importantly, the propagation characteristics of these\nspoof SPPs can be controlled by the surface geometry, opening the way to\nimportant applications such as energy concentration on cylindrical wires and\nsuperfocusing using conical structures.",
