Abstract. This article reports on a study of the dielectric properties of carbon black particles in a polymer matrix at microwave frequencies (0.5- 9.5 GHz). The experimental data was compared to the calculated values obtained by McLachlan and Lichteneker and Rother’s Laws. These both laws did not fit accurately the experimental data for the high concentrations of carbon particles. To overcome this difficulty, these models with adjustable parameters were used with good agreement between the experimental results and calculated values. Nevertheless, the adjustable parameter is not universal and it depends on the frequency.
