A complex pattern with hexagonal lattice and white-eye stripe in dielectric barrier discharge

Abstract A novel type of white-eye pattern in a dielectric barrier discharge system has been investigated in this paper. It is a superposition of a hexagonal lattice and a white-eye stripe in appearance and evolves from a white-eye square grid state with the applied voltage increasing. Its spatio-te...
