Published in 2017 at "Physics of Plasmas"

DOI: 10.1063/1.4978292

Abstract: Microwave pulse propagation through a rapidly created plasma and frequency up-conversion has been demonstrated by the particle-in-cell (PIC) method. Compared with the finite-difference time-domain method in which the time-varying plasma is simplified as a dielectric… read more here.
