Title: THE LORENTZ MODEL APPLIED TO COMPOSITE-MATERIALS
Author: PEDROSO, CB
SANTOS, MB
Abstract: The dielectric functions of composite materials consisting of free-electron-type metal particles (Ag or Cu) and a dielectric host material with epsilon(h) = 1.0, 2.99 or 6.0 are calculated using the Maxwell-Garnett model. These function present an anomalous region when the interband transitions of the metal particles occur at frequencies above the resonance frequency (2epsilon(h) = -epsilon(m)). In this case the Lorentz oscillator model is used to analyse the optical behaviour of the composite material. The Lorentz parameters are calculated and discussed.
