Self-similar plasmonic nanolens as a Vortex Nanogear Transmission

Silver nanolens as a vortex nanogear tansmission. (a) Schematic of a nanolens and an electric field intensity distribution generated by an incoming plane wave. (b) Optical powerflow pattern underlying the nanolens focusing mechanism. (c) Schematic of the nanogear transmission generated in the nanolens. Power flux in each nanogear is looped through nanoparticles.
