Abstract :
This paper describes the principle of the pulsed electroacoustic method (PEA) for space charge profile measurement in lossy and/or dispersive media. The method comprises the following aspects: analyze the principle of the PEA method in lossy and/or dispersive media; estimate the attenuation and dispersion factors in lossy and/or dispersive media; and recover the undistorted waveform from a distorted output signal
