Period Doubling in Glow Discharges: Local Versus Global Differential Conductivity. Modelling, analysis and Simulation (MAS)

摘要

Short planar glow discharges coupled to a resistive layer exhibit a wealth of spontaneous spatio-temporal pattern. Several authors have suggested effective reaction-diffusion-models to explore similarities with other pattern forming ststems. To test these effective models, We here investigate the temporal oscillations of a glow discharge layer coupled to a linear resistor. We find an unexpected cascade of period doubling events. This show that the inner structure of the discharge is more comlex than can be described by a reaction-diffusion-model with negative differential conductivity.
