Enhanced emission and light control with tapered plasmonic nanoantennas: Ivan S. Maksymov, Arthur R. Davoyan, and Yuri S. Kivshar
We introduce a design of Yagi-Uda plasmonic nanoantennas for enhancing the directive gain and achieving control over the angular emission of light. We demonstrate that tapering of nanoantenna elements allows to decrease the inter-element spacing tenfold also enhancing the emission directivity. We fi ... [Appl. Phys.
