Nanocomposites of amorphous metal grains in dielectric matrix are prepared by simultaneous sputtering of complex metallic alloy and SiO2. Electrical conductivity and complex permittiv-ity and permeability are investigated as functions of metallic phase concentration and thermal ageing conditions in a wide frequency range. Conductivity is revealed as very strong func-tion of dielectric concentration. Electromagnetic parameters of amorphous composites exhibit non-linear dependence of com-plex ? and ? on metallic phase concentration in dielectric ma-trix. High values of magnetic losses and close values of ?? and ?? ensure effective absorption of electromagnetic radiation in microwave range that allows using of these nanocomposites as future-technology materials for microwave absorbing-type shields.
