Direct determination of space charge distributions in dielectrics: the pressure wave propagation method

The author reviews the various experimental techniques used to measure charge distributions in dielectrics. He then focuses on the pressure wave propagation method, discussing the principle of the method and techniques of pressure-wave generation. Examples of applications of the pressure-wave propagation method can be found in the fields of high-voltage insulation, piezoelectricity, irradiated materials, and space charge effects are given.<
