Formation of kagome-white-eye-honeycomb hexagonal superlattice pattern in dielectric barrier discharge

A kagome-white-eye-honeycomb hexagonal superlattice pattern is observed in dielectric barrier discharge and studied by two photomultipliers, an intensified charge-coupled device, and a spectrograph. It consists of four sublattices, which are kagome structure, halos of white-eye hexagon, honeycomb frame, and central spots hexagon. As an unconventional symmetry sublattice, the kagome structure results in amazing sublattice discharge order. Based on the consideration that any discharge is related to all previous discharges, a mapping matrix which governs self-organization of the pattern is proposed. These results will promote the development of the pattern dynamics.
