Self-organized pattern formation in an atmospheric-pressure single dielectric barrier discharge

With the advantages of nonvacuum plasma operation, low gas temperature, mild discharge, high yield of active species, etc., atmospheric-pressure DBDs have shown immense potentials for numerous applications. As a spatially extended dissipated system, atmospheric-pressure DBDs with a large number of freedom degrees possess rich and complex temporal nonlinear behaviors including period doubling bifurcation, quasi-periodic behaviors, chaos, etc., and complex spatial nonlinear behaviors including filamentary discharge, self-organized pattern, spatial chaos, etc. A deep understanding of these nonlinear behaviors not only can offer valuable guidance to effective control of the stability and uniformity of atmospheric-pressure DBDs, but also makes it possible to lock atmospheric-pressure DBD operation in a preferred manner to meet the specific application requirements.
