Showing papers on "Surface plasmon resonance published in 1974"
TL;DR: In this paper, the first experimental and theoretical investigation of the coupling of second-harmonic generation of light to surface plasmons in thin silver films was performed, and the results showed that a model based on polarization sources at the silver-air interface correctly predicts the observed harmonic enhancement of one and a half orders of magnitude because of excitation of the surface plasmon.
Abstract: We report the first experimental and theoretical investigation of the coupling of second-harmonic generation of light to surface plasmons in thin silver films. A model of second-harmonic generation due to polarization sources at the silver-air interface correctly predicts the observed harmonic enhancement of one and a half orders of magnitude because of excitation of the surface plasmon.

TL;DR: In this paper, the absorption of light by surface plasmons has been studied using the method of attenuated total reflection, and the reflectance from a quartz-Ag interface has been measured as a function of angle and surface structure for the wavelength region from 3600 to 6000.

TL;DR: In this paper, the resonant excitation of surface plasmons at both the air and substrate surfaces of evaporated Ag films was measured and it was shown that the real part of eAg is a larger negative number at the substrate interface.
Abstract: Measurements of the resonant excitation of surface plasmons at both the air and substrate surfaces of evaporated Ag films indicate that the real part of eAg is a larger negative number at the substrate interface. This difference can be explained with a Maxwell‐Garnett type theory which assumes that the film density near the air surface is several percent below that near the substrate interface.

TL;DR: It is shown that (Al-MgF(2))-interference filters of better performance than have been predicted and obtained previously are possible in the uv below 2500 A.
Abstract: It is shown that (Al-MgF2)-interference filters of better performance than have been predicted and obtained previously are possible in the uv below 2500 A. Experimental results are given for conventional filters of first and higher order and for new filter designs that use multilayer structures for the two mirrors of the filter. All discrepancies between theoretical and experimental results are explained by a coupling of light into the surface plasmon of aluminum via a surface roughness of the MgF2 films.

TL;DR: In this paper, the inelastic scattering probability of low-energy electrons due to the bulk and surface plasmon excitations is calculated using the infinite-square-barrier model.
Abstract: The inelastic-scattering probability of low-energy electrons due to the bulk- and surface-plasmon excitations is calculated using the infinite-square-barrier model. When the dispersion of the plasmons is neglected, the probability becomes the one derived by using the high-frequency step-density model. In order to consider the scattering by the lattices and the absorption effects for an incident electron, the distorted-wave method is used, which upon some manipulation gives essentially the same inelastic intensities as the ones given by Duke and Laramore. Some numerical calculations are performed for the Al(111) surface, and it is found that the absorption plays an important role in determining the intensity for the bulk plasmon relative to the one for the surface plasmon, and the cutoff wave numer at $k=0$ has some influence on the angular profile. The intensities obtained in this paper are qualitatively in agreement with the experimental results.

TL;DR: In this paper, the surface plasmon dispersion relation in the presence of the inhomogeneous surface zone which has been proposed for liquid mercury has been evaluated, assuming that photon-plasmon coupling occurs through the mechanism of frustrated total reflection.
