Abstract

Diverse stable localized states respectively with hexagonal, heptagonal and enneahedral symmetry have been observed in a dielectric barrier discharge system with two water electrodes. The interacting process of different localized clusters due to the attractive interaction is shown. The spatiotemporal dynamics of the localized hexagonal states are measured by photoelectric method. It is found that the seven filaments composing a hexagonal cell discharge nearly at the same time, with the light intensity of the central filament much stronger than its neighboring six ones. Magnifying the light signal, however, it is found that the discharge moment of the central filament always precedes that of others actually.
