Focusing Surface Plasmons with a Plasmonic Lens

Nano Letters, 2005
We report the focusing of surface plasmon polaritons by circular and elliptical structures milled into optically thick metallic films or plasmonic lenses. Both theoretical and experimental data for the electromagnetic nearfield is presented. The nearfield is mapped experimentally using nearfield scanning optical microscopy and plasmonic lithography. We

Surface Plasmons and Singularities

Nano Letters, 2010
We apply the conformal transformation technique to study systematically a variety of singular plasmonic structures, including two-dimensional sharp edges, rough surfaces, and nanocrescents. These structures are shown to exhibit two distinct features.

Surface plasmon immunoassay

Applied Optics, 1990
The most sensitive existing assays used to determine antibody levels in blood serum samples require a tracer material, e.g., radioisotope, fluorofore, or enzyme, to identify the specific analyte. Surface plasmon spectroscopy has been applied recently as a no-label technique for the assay of specific antibody solutions with the antigen proteins ...

Surface-plasmon dispersion and multipole surface plasmons in Al(111)

Physical Review B, 2000
We have measured the collective electronic excitations of the Al(111) surface by means of angle-resolved high-resolution electron-energy-loss spectroscopy. Loss spectra reveal both the monopole and the multipole surface plasmons. The measured dispersion of the monopole surface plasmon is negative, as predicted by calculations of the dynamic response of

Surface plasmon interferometry: measuring group velocity of surface plasmons

Optics Letters, 2007
Optical transmission spectroscopy on metal films with slit-groove pairs is conducted. Spectra of the light transmitted through the slit exhibit Fabry-Perot-type interference fringes due to surface plasmons propagating between the slit and the groove. The spectral dependence of the period of interference fringes is used to determine the group velocity ...

Surface plasmon

2022
Abstract In this chapter, the classical Drude model is used to understand the basic mechanism of plasma wave generation and sub-wavelength propagation, the concept of plasma frequency, the nature of variation of dielectric function, the dispersion relation of surface plasmons in metal-insulator and metal-insulator-metal structures ...

Surface Plasmons and Plasmonics

2020
Surface plasmons (SPs) correspond to self-sustaining excitations of the electron gas of metals or semiconductors, i. e., to modulations of the density of such gas occurring at the surface of the body generating electric fields propagating along the surface and decaying exponentially perpendicular to it.
