Comparison of numerical methods in near-field computation for metallic nanoparticles

Opt Express. 2011 Apr 25;19(9):8939-53. doi: 10.1364/OE.19.008939.

Abstract

Four widely used electromagnetic field solvers are applied to the problem of scattering by a spherical or spheroidal silver nanoparticle in glass. The solvers are tested in a frequency range where the imaginary part of the scatterer refractive index is relatively large. The scattering efficiencies and near-field results obtained by the different methods are compared to each other, as well as to recent experiments on laser-induced shape transformation of silver nanoparticles in glass.
