Abstract

Granular gold and nickel films were prepared by thermal vacuum deposition onto glass substrates. Optical transmittance at near-normal incidence was recorded as a function of the relative mass thickness on each side of the percolation threshold. We show that our transmittance spectra may be described within the framework of Bruggeman's symmetrical approximation for the effective dielectric function with some modifications.
