The dependence of the extinction spectra of three dielectric-core-gold-shell nanocylinder pairs on dimensions. (a) The dependence of the extinction spectra on the pair distance between the three nanocylinder pairs. (b) For the pair distance of 20 nm, the electric field intensity at the wavelength of 979 nm. (c) For the pair distance of 20 nm, the electric field intensity at the wavelength of 1218 nm.
