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…
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…
Scanning Near-Field Optical Coherent Spectroscopy of Single Molecules at 1.4 Kelvin
I. Gerhardt, G. Wrigge, M. Agio +3
We present scanning near-field extinction spectra of single molecules embedded in a solid matrix. By varying the molecule-tip separation, we modify the line shape of the spectra, d…
