Plasmonic nanolens as an internal vortex nanogear transmission. (a) Schematic of the self-similar Ag nanolens proposed in ref 72 (r1 = 45 nm, r2 = 15 nm, r3 = 5 nm, d1 = 9 nm, d2 = 3 nm, ambient index n = 1.0). (b and c) Electric field intensity distribution in the nanolens illuminated on- (b) and off-resonance (c) with the near-field intensity maximum of the nanolens. Far-field (d) and near-field intensity enhancement (e) spectra of the nanolens. (f) The amplitude of the Poynting vector and the phase of the Poynting vector in the x–z plane at the center of the nanolens narrower interparticle gap as a function of wavelength. (g and h) Poynting vector intensity distribution and powerflow around the nanolens off (g) and on (h) the peak intensity wavelength. (i) Schematic of the VNT generated in the nanolens at the peak intensity resonance. Light flux in each nanogear is looped through nanoparticles .
