  The interaction of the visible and ultraviolet electromagnetic P-wave with
the thin flat metallic film localized between two dielectric media is studied
numerically in the framework of the quantum degenerate electron plasma
approach. The reflectance, transmittance and absorptance power coefficients are
chosen for investigation. It is shown that for the frequencies in the visible
and ultraviolet ranges, the quantum power coefficients differ from the ones
evaluated in framework of both the classical spatial dispersion and the Drude -
Lorentz approaches.
