Abstract
Anew mathematical procedure depends on the evolutionary algorithm has been proposed to estimate the optical constants (refractive index, extinction coefficient and thickness) of unknown deposited material on a defined substrate. The transmittance and reflectance experimental data are taken for two materials (Sc2O2 and Rh) with two different thicknesses for the wavelengths range (400-850 nm). The resulting optical constants and the theoretical transmittance and reflectance spectra are very close to the experimental data.
