Patte formation phenomena are investigated in a dielectric barrier discharge under narrow boundary conditions in argon at atmospheric pressure.The discharge shows various scenarios with the increasing applied voltage.This is the first observation of alteating single spot and pair spots patte and of a moving striation patte in a dielectric barrier discharge system.The spatial-temporal correlations between discharge filaments in these pattes are measured by an optical method.The results show that the zigzag patte is an interleaving of two sub-structure pattes, which ignites once for each sub-patte per half cycle of the applied voltage.There is a temporal sequence inversion in consecutive half-cycles for the two sub-pattes.The patte of alteating single spot and pair spots is also an interleaving of two sub-structure pattes.However, the pair spots sub-patte ignites twice and the single spot sub-patte ignites once per half cycle of the applied voltage.
