Development of Self-Organized Filaments in a Microgap Atmospheric Barrier Discharge on Bismuth Silicon Oxide Dielectrics

In this paper, we present subsequent images of self-organized filaments in a microgap atmospheric barrier discharge with and without bismuth silicon oxide (BSO) dielectrics. The images were obtained using an intensified charge-coupled device digital camera. Different developments of the discharge were observed in the region occupied by the filaments in the case of BSO and glass dielectrics. The charge distribution on the dielectric surface played an important role in the development of the self-organized patterns.
