Abstract

EMA model is now used for determination of the components concentrations in heterogeneous materials, prepared as thin (about 1 mkm) films. We can obtain dielectrical function of composite medium (which contain N components) from transmittance and reflectance measurements of the film-substrate system (in the investigated photon energy $HBAR(omega) range substrate must be transparent).
