摘要: In this paper, we investigate the behaviors of patterns in dielectric barrier discharge (DBD) glow and streamer regimes under different operating conditions (driving frequency voltage) external electric/magnetic field to explore similarity difference pattern formation. It is found that both DBDs can be homogenized by decreasing driving a low level. But filamentary streamers still appear at when voltage much higher. With an additional lateral electric field, homogenized. However, axial magnetic makes DBD homogeneous, while decreases size. regimes, dynamics distribution space charges, rather than surface play predominant role formation patterns. charges may also important formation, especially DBD.
