Self-Organized Gas-Discharge Patterns in a Dielectric-Barrier Discharge System

A rich variety of gas-discharge patterns have been observed in a specially designed dielectric-barrier discharge system with two liquid electrodes. The patterns presented here include square-lattice pattern, square-texture pattern, square-superlattice pattern, hexagonal superlattice state, multiarmed-spiral pattern, hollow-hexagonal pattern, and rotating-wheels pattern.
