Paper Abstract

A square pattern is observed in a dielectric barrier discharge system in Ar/air gas mixture. There are two discharge current pulses in each half cycle of the applied voltage. The spatiotemporal dynamics of the square pattern is investigated by an intensified charge-coupled device camera within one discharge current pulse. It is found that the square pattern is an interleaving of two different transient square sublattices, and the evolution of the two sublattices has the time inversion symmetry. Depending on the discharge sequence, the effect of the wall charges on the evolution of the square pattern is discussed briefly.
