Abstract
The pulsed electro-acoustic technique is presented to the Electrical Engineering community where it can find many applications, from the development of improved materials for electrical insulation to the control of electrostatic surface discharge (ESD) phenomena. After a short introduction of the space charge problem, we introduce the technique itself and we show how consistent quantitative information can be extracted from this simple method taking examples of dielectrics under field or charged by an electron beam. Non-polar and polar materials are considered and it is shown that space charge and polarization effects can be separated from the spectra analysis. In a last part, we review new perspectives open by this technique to understand and to model electrical transport in dielectrics
