We have theoretically investigated the dynamics of the scattering of surface-plasmon polariton (SPP) pulses by single nanoscale metal defects through a rigorous calculation of the time dependence of the reflected and transmitted SPP and of the angular distribution of the scattered light. SPP resonances that occur at deep Gaussian grooves are probed with SPP pulses, the resonant scattering being unequivocally manifested by (a) the exponential tails of the scattered SPP and light pulses and (b) the delay time of the transmitted SPP pulse.

  14. Drude's free-electron approximation describes correctly the metal response for frequencies below the onset of the highly absorbing, interband transitions (at l~400 nm for Ag). The (weak) absorptive contribution to Drude's formula is also neglected, since it does not introduce significant effects in the scattering process (defect size < <labs), and subsequent dissipative losses in the SPP propagation can be independently accounted for (labs~24μm for Ag at l=650 nm).
