The Plasmon Dispersion Relation on a Rough Surface: A Simple Approximation.

Abstract

This paper is concerned with periodic, laser induced, chemical vapor deposition recently observed experimentally. In order to inquire further into this phenomena, it is first necessary to find a simple means of calculating the plasmon field strength for relatively deep gratings. The Rayleigh hypothesis is assumed, and only p-polarized, normally incident light is considered. A closed form equation for the plasmon field intensity is then derived. Also discussed is the behavior of the plasmon dispersion relation for a shallow grating, but for a complex dielectric constant where the imaginary part is not necessarily small. Keywords: Plasmon dispersion relation; Rough surface; Chemical vapor deposition; Rayleigh hypothesis; Polarized light; Complex dielectric constant.
