Theory of Dipole Orientation Process in the Dielectric Based on the Concept of a Visco-Elastic Model—Part I

Abstract

It has been shown that the process of dipole orientation in a dielectric may be likened to the mechanical behaviour of a visco-elastic element consisting of an ideal spring in parallel with an ideal dash pot. The elasticity of the spring and the viscosity of the dash pot are different from the ordinary macroscopic elasticity and viscosity of the material, and expressions for these phenomenological quantities have been derived from molecular kinetics. An expression for the time of relaxation has been derived and it has been pointed out that there cannot be a correlation between the mechanical and dielectric properties of substances except polymers, in which the processes of dipole orientation and mechanical deformation are similar and a correlation may be expected in these substances.
