摘要: In this work we start with a limited but directed historical review of dielectric literature emphasizing the assumptions underlying dielectric theory. We outline the work of Debye1"3 who developed the idea of point dipoles in neutral molecules. With the development of this idea he was able to explain why the dielectric constants of materials were greater than the square of the refractive index. Fixing these dipoles to spheres and assuming vicious drag forces to impede their motions lead to the now famous Debye relaxation process. With the development of this idea he was able to explain why relaxation were "anomalous" when compared to absorption curves at optical and infrared frequencies. These two contribu-tions form a very profound and broad starting point in the field of dielectric relaxation theory and interpretation. For example, the point dipole concept was used by Onsager, Kirkwood, Frohlich, Scaife, Cole, and others as starting points for their theories,4""8 to correct the inconsis-tencies of Debye's equilibrium theory with experimental results. The Debye process is used by all those who wish to discuss broad and skewed dielectric relaxation dispersions in terms of a distribution of Debye elements. Nearly all dielectric literature since his developments is based on these concepts, and seldom if ever are the underlying limitations inspected for their suitability.
