“…2͑a͒, similar to that previously reported. 4,10 The width of the current pulse was about 2 s, a fraction of the voltage period of 100 s. The peak current was 1.75 mA/ cm 2 now, some 60 times larger than that in Fig. 1͑a͒.…”

“…Over the past five years, considerable advance has been made both in their scientific understanding and in their technological capability, benefited from a series of systematic studies of plasma dynamics both theoretically [6][7][8][9] and experimentally. [10][11][12][13] It is widely recognized that an in-depth understanding of plasma dynamic behaviors of atmospheric DBDs is likely to be indispensable to their future development.…”

“…4,6,7 Subsequent experimental and computational studies have suggested that it is also possible to obtain several discharge current pulses every half voltage cycle. [8][9][10] This suggests that the discharge system remains spatially homogeneous while it undergoes periodic temporal variations. In nonlinear science, such periodic temporal variation is generally known as oscillation.…”

. Complex dynamic behaviors of nonequilibrium atmospheric dielectric-barrier discharges.Journal of Applied Physics, 100 (6), article 063304, pp. 1-9.Additional Information:• In this paper, a one-dimensional fluid model is used to investigate complex dynamic behaviors of a nonequilibrium dielectric-barrier discharge ͑DBD͒ in atmospheric helium. By projecting its evolution trajectory in the three-dimensional phase space of gas voltage, discharge current density, and electrode-surface charge density, the atmospheric DBD is shown to undergo a sequence of complex bifurcation processes when the applied voltage is increased from prebreakdown to many times of the breakdown voltage. Once the gas voltage exceeds the breakdown voltage, the discharge plasma is found to acquire negative differential conductivity and as a result its stability is compromised. For atmospheric DBD, however, the resulting low plasma stability is mitigated by a rapid accumulation of surface charges on the electrodes, thus allowing the atmospheric DBD to retain their character as a glow discharge. At certain values of the applied voltage, a highly complex phenomenon of period multiplication is observed in which the period of the discharge current is three times that of the applied voltage. This suggests that nonequilibrium atmospheric DBD may support evolution patterns that are quasiperiodic or even chaotic. These complex dynamic behaviors are likely to be critical to a full understanding of plasma stability of nonequilibrium atmospheric discharges and to the development of their instability control strategies.

“…With a larger gap voltage, it is possible to trigger several discharge events every half-cycle of the applied voltage and the peak density of these discharge events is markedly higher than that in the case with one discharge event every half-cycle. 4,5 This study considers APGD with modest current densities and with only one discharge event every halfcycle of the applied voltage.…”

“…So far most numerical simulations of helium APGD have been confined to one dimension. 2,[4][5][6]9,10 In this contribution, we present a two-dimensional ͑2D͒ fluid model in a cylindrical symmetric coordinate system to study the radial evolution of APGD when the discharge current density is low ͑Ͻ10 mA/ cm 2 ͒ and there is one current peak every half cycle of the applied voltage.…”

. Two-dimensional simulation of a low-current dielectric barrier discharge in atmospheric helium.Journal of Applied Physics, 98 (11), article no. 113308, pp.1-6.Additional Information:• A two-dimensional computational study is presented to unravel radial structure of a dielectric barrier discharge in atmospheric helium when the gas voltage exceeds slightly the breakdown voltage and the discharge current is low to retain a repetitive dynamic pattern of one discharge event every half cycle of the applied voltage. Simulation results reveal that during each half cycle of the applied voltage gas breakdown occurs first in a central region around the electrode axis. After it is extinguished, a second breakdown is triggered in the boundary region near the radial edge of the two electrodes as confirmed by the dynamic evolution of the radial profile of the electric field, the current density and the charged particles. These predictions are consistent with relevant experimental observations in literature. It is also shown that an increase in the applied voltage or in the excitation frequency reduces the time delay between the two breakdown events and the difference between their corresponding current densities. This offers a route to improve the uniformity of atmospheric dielectric barrier discharges for their intended applications.
