Abstract

Measurements of the refractive index of discontinuous metallic films, consisting of gold clusters embedded in a dielectric matrix prepared in a capacitively coupled coplanar diode radio frequency discharged system, are reported.

These composite films were analyzed to determine the metal volume fraction, the thickness and the cluster size.

Optical characterizations in the visible and near infrared regions of the electromagnetic spectrum, particularly, in the near-IR region (Nd/YAG laser wavelength 1.0642 μm), where the absorption coefficient of these materials is very low (k < 0.001) were performed. Optical guided modes analysis allowed careful measurement of the effective medium refractive index.
