“…The di!usive scattering of the second harmonic from the metal-dielectric "lm has been observed in experiments with C -coated semicontinuous silver "lms [124]. The di!usely scattered second harmonic generation was also observed from thin but continuous silver "lms [125] on which surface plasmon mode was excited in the Kretschmann geometry.…”

“…About three decades ago, monochromatic-light experiments were performed on dielectric (C 60 − and SiO x − ) coated Ag island films to study the SHG and the sensitivity of the generated harmonic to the surface properties was emphasized. An order of magnitude enhancement in the SH response was observed in the coated Ag island films as compared to the uncoated ones 73 .…”

Second-order nonlinear optical processes do not manifest in the bulk of centrosymmetric materials, but may occur in the angstroms-thick layer at surfaces. At such length scales, quantum mechanical effects come into play which could be crucial for an accurate description of plasmonic systems. In this article, we develop a theoretical model based on the quantum hydrodynamic description to study free-electron nonlinear dynamics in plasmonic systems. Our model predicts strong resonances induced by the spill-out of electron density at the metal surface. We show that these resonances can boost second-harmonic generation efficiency up to four orders of magnitude and can be arbitrarily tuned by controlling the electron spill-out at the metal surface with the aid of thin dielectric layers. These results offer a possibility to artificially increase nonlinear susceptibilities by engineering optical properties at the quantum level.

“…The diffusive scattering of the second harmonic from metal-dielectric films has been observed in experiments with C 60 -coated semi-continuous silver films (Aktsipetrov et al, 1993) and from thin but continuous silver films (Kuang and Simon, 1995). One may argue that the diffusive scattering of 2ω field is due to the anomalous fluctuations of local electric fields on the rough features of the surface with the spatial scale a being much smaller than wavelength λ of the incident light.…”

Mechanics and Materials R.V. KohnSystems and Control S.S. Sastry, P.S. Krishnaprasad Problems in engineering, computational science, and the physical and biological sciences are using increasingly sophisticated mathematical techniques. Thus, the bridge between the mathematical sciences and other disciplines is heavily traveled. The correspondingly increased dialog between the disciplines has led to the establishment of the series: Interdisciplinary Applied Mathematics.The purpose of this series is to meet the current and future needs for the interaction between various science and technology areas on the one hand and mathematics on the other. This is done, firstly, by encouraging the ways that mathematics may be applied in traditional areas, and well as point towards new and innovative areas of applications; and, secondly, by encouraging other scientific disciplines to engage in a dialog with mathematicians outlining their problems to both access new methods and suggest innovative developments within mathematics itself.The series will consist of monographs and high-level texts from researchers working on the interplay between mathematics and other fields of science and technology.
