This work deals with the design and prediction of the dielectric characteristics of two- and three-component composite materials by the computer modeling and by the experimental validation. The modeling of the materials is executed in Phi3d electric field calculating package, based on the algorithm which solves Laplace equation using boundary integral equation method (BIEM). The complex effective permittivity of the composite materials is studied in function of frequency in the range 50 Hz – 1 MHz, in the quasi-static approximation, and in function of the filler inclusions concentration and their shapes. The experimental validation is carried out on material samples elaborated in laboratory. The studied composites are two- and three-phase m...
