Nonlinear phenomena in dielectric barrier discharges: pattern, striation and chaos

The nonlinear phenomenon is very popular in dielectric barrier discharge (DBD) plasmas. There are at least three kinds of spatial and temporal nonlinear phenomena appearing synchronously or asynchronously in DBDs, i.e. self-organized patterns, striations and chaos. This paper describes the recent research and progress in understanding the nature of these nonlinear phenomena. Patterns are macroscopic structures with certain spatial and/or temporal periodicities generated through selforganization of microscopic parameters. The physics of patterns in DBDs is mainly associated with lateral dynamic behaviors or the lateral non-local effect of charged particles resulting in the lateral development or non-uniformity of discharge. Striations are ionization waves with unique properties determined by transport phenomena, ionization processes and electron kinetics in current-carrying plasmas. The physics of striations in DBDs is mainly associated with the advances in non-local electron kinetics in spatially inhomogeneous plasmas. Chaos is a kind of random and non-periodic phenomenon occurring in a determined dynamic system, following a series of certain rules while exhibiting random locomotion, and is regarded as an intrinsic and ubiquitous phenomenon in a nonlinear dynamic system. An evolution trajectory including period-doubling bifurcation to chaos was observed in DBDs or DBD-derived plasmas. In a common sense, it is believed that the formation of all the three nonlinear phenomena in a DBD system should be related to the non-local transversal and/or longitudinal dynamics of space charges (i.e. non-local effect) or the localized electric field interaction. Future work is still needed on the underlying physics and should be directed to pursuing the unification of these nonlinear phenomena in DBD.

“…The role of space charges on striation dynamics in PDP cells is not fully understood. Recently, striations in micro-discharges with a hollow anode covered by dielectric were studied in the numerical experiments [101] via three-dimensional PIC simulations. Striations appeared in Ne, Ar and Xe for the reduced electric fields E/p ∼ 50 V (cm Torr −1 ).…”

This paper describes the recent progress in understanding the nature of striations in rare gas plasmas. Striations are ionization waves with unique properties determined by transport phenomena, ionization processes and electron kinetics in current-carrying plasmas. Recent progress in understanding the physics of striations is mainly associated with the advances of non-local electron kinetics in spatially inhomogeneous plasmas and the development of computational models of gas discharges. It has been proven that kinetic analysis of electrons is necessary for nearly all types of striations. Most strikingly, the non-hydrodynamic behaviour of electrons reveals itself in kinetic resonances of the electron distribution function in spatially periodic electric fields, resulting in a variety of striations at low pressures. Moving striations in classical dc discharges have been obtained in computer experiments. Renewed interest in striations has been recently generated by the observation of striations inside pixels of plasma display panels and other micro-plasma devices. High sensitivity of striations to the state of electron gas and ionization kinetics makes them an ideal tool for testing discharge models and advanced plasma diagnostics. Further studies of striations in glow discharges could shed light into the physics of different plasma sources used in modern technologies.There are more things between cathode and anode than are dreamt in your philosophy.H Raether

“…The transverse self-organized patterns in glow DBD system can be reproduced by using dynamic simulations (i.e., fluid models [16][17][18][19]). But the longitudinal striations in DBD system can only be reproduced by kinetic model like PIC-MCC [22][23][24][25][26][27].…”

“…4. The above process is typical for striation forming above the dielectric surface in many DBD configurations [22][23][24][25][26][27]. From this viewpoint, the plasma generates during the striation formation rather than the striations emerge in the striated plasma background.…”

Simultaneous formation of striations and patterns in surface dielectric barrier discharge

Longitudinal striations and transverse patterns are simultaneously observed in a surface dielectric barrier discharge (DBD) system in argon. Patterned filaments form at sufficient high frequency and moderate voltage. The images of bright filaments and faint regions between them reverse alternately in the two half-cycles. The number of luminous filaments is generally determined by the gas pressure rather than the applied voltage. The striations appear during the plasma expanding above the anode surface in negative half-cycle, in the filaments as well as the regions between them synchronously. The striation spacing does not depend on the voltage, but decreases with the gas pressure in the present configuration. The formations of striation and pattern are two separated processes, and both relate strongly to the accumulated charges on the dielectric surface and the induced surface field.
