Optical properties of glasses or films containing nanoclusters: a numerical simulation

Résumé

A numerical simulation was developed in order to determine the linear optical properties of an inhomogeneous medium. The method, based on a volume integral equation, takes multiple scattering into account. Consequently, it allows one to deal with media with high concentrations of inhomogeneities for which interactions between particles become significant and analytical theories often fail to predict the optical properties. It is shown that the simulation can be used as a reference solution in comparing the validity domain of different analytical theories. Then, the dielectric anomaly is studied when metallic clusters are situated close to a vacuum dielectric interface. The influences of the inclusions filling fraction, the interface and the distribution function of the position of the particles are analyzed.
