Results for a d = 20 nm aluminum nanoparticle. (a) Extinction, scattering, and absorption efficiencies. Inset: complex dielectric constant of aluminum. (b) Radiated power enhancement for dipoles spaced s = 5 and 10 nm from the nanoparticle calculated with the FDTD method (solid curves), and with analytical theory (dashed curves). The dipoles are oriented perpendicular to the metal surface.
