The electrical network model and differo-integral method (D-IM) were applied to electrical parameters estimation of nonhomogeneous composite materials. The laminar composite is arranged of conductive unit cells with adjustable geometry. Modification of unit cell's internal geometry results in change of composite's effective properties. Stationary electric and magnetic fields of exemplary structures were numerically analyzed. Theoretical computations along with network model were verified by experimental measurements of 10 fabricated samples. Obtained results indicate that D-IM is a valuable tool for qualitative and quantitative estimation of electrical parameters.
