Breakdown of Debye’s Model for Dielectric Relaxation in High Frequencies

Abstract

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.
