The influence of driving frequency on the discharge regime of a homogenous dielectric barrier discharge in argon at atmospheric pressure is studied through a one-dimensional self-consistent fluid model. The simulation results show that the discharge exhibits five notable discharge modes, namely the Townsend mode, stable glow mode, chaotic mode, asymmetric glow, and multiple period glow mode in a broad frequency range. The transition mechanisms of these modes should be attributed to the competition between the applied voltage and the memory voltage induced by the surface charges.

“…In the previous work, it has been numerically shown that the discharge can undergo a transition from a normal period-one operation to chaos via period-doubling bifurcation as the frequency [7][8][9][10][11] or the amplitude [12,13] of the applied voltage is increased, or via a route of a quasiperiodic torus by increasing the driving frequency [14]. Moreover, experimental observations (a) E-mail: ddai@scut.edu.cn on period-doubling bifurcation and chaos in atmospheric plasma jets [15][16][17][18] and in DBDs at atmospheric pressure under a parallel electrode configuration [19] are reported which confirm the existence of such nonlinear phenomena in a real experimental implementation.…”

Period-doubling bifurcation has been frequently observed in the numerical simulations of atmospheric dielectric barrier discharges and it also has been partly confirmed in our previous experiments. In this letter, we report inverse period-doubling bifurcation in an atmospheric helium dielectric barrier discharge. Experiments are carried out under parallel electrode configuration. By only increasing the amplitude of the applied voltage, we observe that the discharge successively experiences chaos, period-four, period-two and period-one. As well as the experimental waveforms, the fast Fourier transform of the discharge current is given to qualitatively demonstrate the state of the discharges. Although the observed bifurcation behavior is seemingly similar to the wellknown period-doubling bifurcation, it is essentially a different type of bifurcation behavior which has never been experimentally reported in the atmospheric dielectric barrier discharges. As a strongly nonlinear temporal-spatial system, the atmospheric dielectric barrier discharge could present far more complex behaviors under certain conditions than we thought. Further studies are still required to better understand the underlying mechanism of these complex behaviors.

“…Recently, these nonlinear behaviors have been widely observed by numerical simulation and experiment. [7][8][9][10][11] Significant advances have been made both in their fundamental mechanism and in their dependence on the discharge parameters. But most of these papers focused on the parallel plate structure and needle-plate structure.…”

The discharge characteristics and temporal nonlinear behaviors of the atmospheric pressure coaxial electrode dielectric barrier discharges are studied by using a one-dimensional fluid model. It is shown that the discharge is always asymmetrical between the positive pulses and negative pulses. The gas gap severely affects this asymmetry. But it is hard to acquire a symmetrical discharge by changing the gas gap. This asymmetry is proportional to the asymmetric extent of electrode structure, namely the ratio of the outer electrode radius to the inner electrode radius. When this ratio is close to unity, a symmetrical discharge can be obtained. With the increase of frequency, the discharge can exhibit a series of nonlinear behaviors such as period-doubling bifurcation, secondary bifurcation and chaotic phenomena. In the period-doubling bifurcation sequence the period-n discharge becomes more and more unstable with the increase of n. The period-doubling bifurcation can also be obtained by altering the discharge gas gap. The mechanisms of two bifurcations are further studied. It is found that the residual quasineutral plasma from the previous discharges and corresponding electric field distribution can weaken the subsequent discharge, and leads to the occurrence of bifurcation.
