Abstract
Detailed knowledge of the electric charge or field distribution in the bulk of dielectrics is necessary for the understanding of charge-storage and charge-transport phenomena. The most successful techniques for the experimental determination of spatial charge or field distributions in dielectrics, are based on the transit of a compression wave through the sample [1-6]. In the present study, the basic equations for pressure-pulse and pressure-step experiments are derived from first principles. The pressure dependence of the relative permittivity e is investigated, and the influence of this dependence on the signal amplitude is calculated for nonpolar and for polar dielectrics. The response equations for pressure-step, pressure-pulse and arbitrary pressure-profile experiments are calculated.
