Light scattering by an oscillating dipole in a focused beam
Gert Zumofen, Nassiredin M. Mojarad, Mario Agio
The interaction between a focused beam and a single classical oscillating dipole or a two-level system located at the focal spot is investigated. In particular, the ratio of the sc…
Metal nanoparticles in strongly confined beams: transmission, reflection and absorption
Nassiredin Mojarad, Gert Zumofen, Vahid Sandoghdar +1
We investigate the interaction of tightly focused light with the surface-plasmon-polariton resonances of metal nanospheres. In particular, we compute the scattering and absorption…
Tailoring the excitation of localized surface plasmon-polariton resonances by focusing radially-polarized beams
Nassiredin M. Mojarad, Mario Agio
We study the interaction of focused radially-polarized light with metal nanospheres. By expanding the electromagnetic field in terms of multipoles, we gain insight on the excitatio…
Perfect Reflection of Light by an Oscillating Dipole
G. Zumofen, N. M. Mojarad, V. Sandoghdar +1
We show theoretically that a directional dipole wave can be perfectly reflected by a single point-like oscillating dipole. Furthermore, we find that in the case of a strongly focus…
Plasmon spectra of nanospheres under a tightly focused beam
Nassiredin M. Mojarad, Vahid Sandoghdar, Mario Agio
We study the modification of the far-field cross sections and the near-field enhancement for gold and silver nanospheres illuminated by a tightly focused beam. Using a multipole-ex…
