Hybridly Polarized Nanofocusing of Metallic Helical Nanocone

We present a metallic helical nanocone, which is a combination of a helical structure and a conic structure. Surface plasmon poloritons are excited at the boundary of the bottom of the helical nanocone, then guided and rotated by the groove provide by the helical structure on the nanocone, and final...
