Abstract

The MAGIC2D finite difference electromagnetic particle-in-cell (FDTD EM-PIC) code has been upgraded to include particle number controls for plasmas modeled by a hybrid particle-conductivity treatment following guidelines developed for SGEMP codes. PIC code solutions to plasma problems become more practical compared to uncontrolled particle number growth which can occur from electron avalanche as electric fields are quenched. Criteria for setting parameters for the new features in plasma calculations are discussed, and comparison is made to measured dielectric barrier discharge (DBD) plasma actuator neutral particle velocities.
