BREAKDOWN OF DEBYE MODEL FOR DIELECTRIC-RELAXATION IN HIGH-FREQUENCIES

Although Debye's relaxation model has been extensively used in analyzing experimental data of dielectric dispersion and absorption, the model has a fault to violate the sum rule for dielectric function. A simple and tractable modification to Debye's model is proposed which is free from the above-mentioned fault. The resulting Cole-Cole diagram is shown to deviate from an exact circle.
