Abstract. By means of ion-beams raising onto lavsan foundation of great area (up to ) the nano-granulated films by type of “metal-dielectric” having composition: , , ,  are grown. Onto the films area it is investigated the distribution of thickness, concentration and relative value of metal-phase and also static and dynamic conductivity. It is found the great (on two order and more) exceeding of dynamic conductivity over static conductivity taking place on films with dielectric matrix , caused by low static conductivity of dielectric phase (about ). The received results are explained by the model of intergranular currents.

Key words:  thin films, nanocomposit metal-dielectric, electromagnetic wave reflection.
