In this paper, the interaction between an oscillating dipole moment
and a Silver nanoparticle has been studied. Our calculations are
based on Mie scattering theory and discrete dipole
approximation(DDA) method.At first, the resonance frequency due
to excitingthe localized surface plasmons has been obtained using
Mie scattering theory and then by exciting a dipole moment in
theclose proximity of the nanoparticle, the induced charge
distribution on the nanoparticle surface has been calculated. In our
calculations, we have exploited the experimental data obtained by
Johnson and Christy for dielectric function.
