Optical effect of the substrate on the anomalous absorption of aggregated silver films
TLDR
In this article, the optical effect of the substrate on the anomalous absorption of aggregated silver films is taken into account in terms of the dipole interaction between an island particle and its mirror image in the substrate.About:

Surface-enhanced Raman scattering
TL;DR: In this article, the authors developed a surface-enhanced Raman scattering (SERS) model of adsorbates on metal surfaces, where the long-range enhancement by resonances of the macroscopic laser and Stokes field is separated quantitatively from the metal electron-mediated resonance Raman effect.

TL;DR: In this article, the basic physics and applications of planar metamaterials, often called metasurfaces, which are composed of optically thin and densely packed planar arrays of resonant or nearly resonant subwavelength elements, are reviewed.

Extremely narrow plasmon resonances based on diffraction coupling of localized plasmons in arrays of metallic nanoparticles.
TL;DR: It is shown experimentally that reflection from an array of nanoparticles can be completely suppressed at certain wavelengths, and metal nanostructures exhibit pi-jump for the phase of the reflected light.

TL;DR: A nanofabricated medium consisting of electromagnetically coupled pairs of gold dots with geometry carefully designed at a 10-nm level exhibits a strong magnetic response at visible-light frequencies, including a band with negative µ.

Colours in Metal Glasses and in Metallic Films
TL;DR: In this paper, it was shown that the presence of many of these minute spheres to a wave-length of light in the glass will account for all the optical properties of "regular" gold ruby glass, and that the irregularities in colour and in polarisation effects sometimes exhibited by gold glass are due to excessive distance between consecutive gold particles or to excessive size of such particles.

Colours in Metal Glasses, in Metallic Films, and in Metallic Solutions. II
TL;DR: In this paper, it has been shown that the first stage in the formation of a crystal of those metals is the small sphere; and from observations on the growth of sulphur crystals in CS2, Vogelsang arrived at the conclusion that the small spheres is always the first phase in forming a crystal. But it is by no means necessary that each of these small spheres, formed as crystallisation commences, should give rise to a separate crystal.

Optical Properties of Ag and Cu
H. Ehrenreich,H. R. Philipp +1 more
TL;DR: In this paper, experimental data for the optical constants of Ag and Cu extending to 25 eV are discussed in terms of three fundamental physical processes: (1) free-electron effects, (2) interband transitions, and (3) collective oscillations.

Optical Properties of Thin Metallic Films in Island Form
TL;DR: In this article, the optical absorption of island films of gold was studied as a function of island density, as determined from electron micrographs and film thickness, and the absorption band resulting from a bounded plasma resonance in the particles was shifted to longer wavelengths as the island density increased.
