A computational study of the optical response of strongly coupled metal nanoparticle chains

摘要: We study the optical response of strongly coupled metal nanoparticle chains using rigorous multiple scattering calculations. The collective resonant frequency silver nanosphere and coupling between are considered. understood by transmission reflection calculations 2D periodic arrays nanospheres. results in agreement with recent experiments. splitting plasmon resonance modes for different polarizations incident light explored. Our show that transverse mode wavelength is very sensitive to inter-chain distance. Results on effect disorder also presented.
