Abstract

Abstract

The perfectly matched layer(PML) medium equations for Gaussian unit were derived based on the basic idea of Benrenger’s PML and the numerical validation and parameter optimization were done. The corresponding absorbing boundary module was added into the 2D3V PIC software PLASIM, achieving good absorption with low reflection. In addition, this module is proved applicable by simulating the propagation of a nanosecond laser prepulse in an underdense plasma.
