Abstract
The T-matrix formalism developed by Waterman and extended to clusters by Peterson and Ström is used to calculate local electric fields for single spherical and spheroidal metallic particles as well as for two-particle clusters. The calculations are done in the electrodynamic regimes as well as in the long-wavelength regime. Radial dependence, angular distributions, and multipolar composition of resonances are analyzed for all cases. Comparison with calculations of local fields by recent electrostatic formulations of the problem are performed. The failure of the multiple-scattering approach for clusters with scatterers in close proximity in the long wavelength regime is discussed. The existence of a critical interparticle distance at which occurs a maximum enhancement for clusters of two ellipsoidal particles is obtained. The versatility of the T-matrix method for calculating the local field in the neighborhood of clusters made up of arbitrary scatterers is demonstrated.
