Simulation of nonlinear wave particle interactions in space plasmas using the VHS technique

Summary form only given, as follows. A technique for the numerical simulation of nonlinear wave particle interactions in a collision free space plasma is reported. The problem considered is the interaction between a continuous distribution of hot electrons and narrowband or quasi-narrowband electromagnetic radiation in the VLF band (4 kHz). These nonlinear wave-particle interactions cause a wide variety of phenomena in the VLF band, most notably triggered VLF emissions. In this study, a rising frequency emission has been simulated. An efficient technique termed Vlasov hybrid simulation (VHS) has been used. The key feature of this technique is described.<>
