Peculiarities of light scattering by nanoparticles and nanowires near plasmon resonance frequencies

Abstract

Results related to the peculiarities of light scattering by nanoparticles and nanowires near plasmon resonance frequencies are reported. It is shown that the scattering problem for weakly dissipative media cannot be analyzed in the dipole approximation, in contrast to the classical Rayleigh scattering. A structure of the Poynting vector in the near field area is obtained. It is shown that small variations of the size parameter or/and the incident light frequency may lead to drastic transformations of the near field distribution. © 2007 IOP Publishing Ltd.
