Paper Abstract

Model and experimental investigations of electrodynamic properties of tunable structures from liquid-impregnated porous magnetic media are presented. Microwave spectra of complex permittivity and permeability of dry and liquid- impregnated media with ethyl alcohol or water-alcohol mixtures were measured. Real and imaginary parts of permittivity were found to exceed the upper Wiener boundary. Dielectric and magnetic properties of liquid-impregnated porous ferrite media were modeled using non-local volume averaging theory (VAT). This approach accounts for several hierarchical levels and morphology of the system.
