Surface Plasmon Dependence on the Electron Density Profile at Metal Surfaces

ACS Nano, 2014
Abstract We use an extension of the hydrodynamic model to study nonlocal effects in the collective plasmon excitations at metal surfaces and narrow gaps between metals, including the surface spill-out of conduction band electrons. In particular, we simulate metal surfaces consisting of a smooth conduction-electron density profile and ...

Electron Density Profile Calculation Technique for Autoscala Ionogram Analysis

open access: yesAdvances in Space Research, 2009
An electron density profile model with free parameters is introduced. Initially the parameters are calculated on the basis of the ionospheric characteristics automatically obtained from the ionograms by Autoscala and considering the helio- geophysical ...

Electron Density Profiles of Nerve Myelin

Nature, 1971
THE structure of the nerve membranes within the myelin sheath of frog sciatic nerve has been studied by low-angle X-ray diffraction. Many additional orders of diffraction have been recorded from nerve, and, from a structure analysis of this new X-ray data, a twelve-parameter electron density model is proposed.
