Contribution to the Study of Optical Properties of a Dielectric Medium (Atomic Vapor) Using the Lorentz Model

Abstract

Optical properties of a dielectric medium consisting of an atomic vapor are investigated theoretically using the model of elastically bound electrons. This model describes the interaction of an electromagnetic field with the bound electrons to the vapor atoms [7]. In this paper, we propose a formalism which takes into accurate the effect of the number of electrons on the vapor index. We use the approximation of free electrons (no interaction between free electrons).
