Showing papers on "Surface plasmon resonance published in 1972"
TL;DR: In this article, the frequency and linewidth of surface plasmons in doped germanium and in gold and surface phonons in calcium molybdate are determined.
Abstract: A method is described of directly coupling an optical beam to surface excitations. Using this technique the frequency and linewidth of surface plasmons in doped germanium and in gold and surface phonons in calcium molybdate are determined. The method also allows the dispersion curve to be measured.

TL;DR: In this article, an electromagnetic analysis of a black-box type yields a general model-independent surface plasmon dispersion relation, which confirms and extends the validity of Harris and Griffin's formula 2 in terms of the charge density fluctuation and its dipole moment, but it shows furthermore that there is an extra term due to surface current fluctuations.

TL;DR: In this article, the authors measured the reflectance at photon energies in the vicinity of the surface plasmon energy (1000-1600 A) and showed that the surface roughness is a function of the dielectric's thickness.
Abstract: Different roughnesses induce changes of the interaction of incident light with surface-plasma oscillations. We observed those changes in the optical properties of aluminum. Identical aluminum films were deposited in ultrahigh vacuum (uhv) on substrates of varying roughnesses. We measured the reflectance at photon energies in the vicinity of the surface plasmon energy (1000–1600 A). We used overcoated substrates of different dielectrics (CaF2, MgF2, and LiF). In the terms of existing theories, we show that the curves are conveniently interpreted by taking into consideration (a) the light scattering by the surface characterized by the rms roughness σ and (b) the plasmon-photon interaction closely related to the roughness σand correlation length a. Thus, within the limit of accuracy (ΔR = ±0.5%) the roughness can be determined; σ is a function of the dielectric’s thickness with Δσ<0.5 A and the correlation length a (5 A<Δa<10 A) appears to be a characteristic of the nature of the dielectric. A study under an electron microscope confirms the theoretical strong value of roughnesses and shows the condensation process of aluminum on the rough substrates.

TL;DR: In this paper, a hologram was made using a surface plasmon resonance wave as the reference beam, which was stimulated on a 1200-line/mm aluminum reflection grating that was coated with a thin layer of high-resolution photographic emulsion.

TL;DR: In this article, the plasmon threshold experiment reported in the preceding paper is analyzed and implications on surface and volume plasmmon dispersion laws are drawn, and it is concluded that there does not exist today any theoretical surface plasmor dispersion law able to describe the experimental result for short wavelengths.
