Simple method for the dielectric relaxation function investigation

Abstract A new simple method for determination of the numerical parameters of dielectric relaxation functions is presented. This analysis method uses a logarithmic scale for the time axis and the first derivative of relaxation function. Three reference points for the relaxation function are found; and new numerical parameters at these points are defined. The analysis of the Kohlrausch–Williams–Watts relaxation function is carried out. A number of useful formulas relating to the KWW exponent and the newly introduced numerical coefficients are found. The presented method gives the numerical parameters of a relaxation function and provides the new opportunities for dielectric studies.
