Laser-intensity modulation method (LIMM)-an analytical and numerical modification

An analytical method that has been used with the laser intensity modulation technique for the determination of polarization and space-charge distributions in electrically stressed low-density polyethylene is described. A numerical method and data analysis are presented. In the analysis, a specific model of spatial distributions of space charge and polarization has been assumed that appears to provide reasonable agreement between the experimentally observed and the expected results.<
