Abstract
Tuning of the resonant state of a structure that scatters optical fields is achieved by varying the effective optical properties of the environment of a small conductive structure. The frequency tunable resonant scatterer includes a medium, a conductive structure within that medium and a second structure in the vicinity of said conductive structure, wherein the plasmon resonance of said conductive structure is tuned by way of the proximity of said second structure to said conductive structure. The second structure is gradually moved away from and closer to the nanoparticle to change the effective dielectric constant for tuning a resonance frequency of the conductive structure to plural excitation wavelengths.
