Abstract: Based on the formulas of effective permittivity and permeability of granular media derived from the strong fluctuation theory, the influence of the shapes of wave-absorbing particles was discussed. From the theory, the optimum shape of wave-absorbing particles was recommended and the prediction formulas of permittivity and permeability for ferrite wave-absorbing materials were given. It has been found that the experimental results are in good agreement with theoretic. The work would be helpful to the design of antiradar coating materials.

Key words: permittivity, coating materials, wave-absorbing materials, permeability
