The Project uses modeling and simulation to investigate the dynamics of microplasmas. The focus is on boundary sheaths, planar microdischarges, micro thin cathode discharges, microcavity arrays, and pulsed corona sources. Two complementary approaches are used. The "hybrid" approach employs two- or three-dimensional self-consistent numerical codes to describe the behavior of all species (electrons, ions, excited, and ground-state neutrals) and all interactions (elastic and inelastic collisions, emission and absorption of radiation, interactions with the walls). The "focussed" approach discusses specialized models which contain only the most important interactions, reduce the dimensionality, or represent only parts of the discharges. Comparison of the models and the experiments will uncover the exact operation mechanism of the discharges.

该项目使用建模和仿真来研究微等离子体的动力学。重点是边界鞘、平面微放电、微薄阴极放电、微腔阵列和脉冲电晕源。使用了两种互补的方法。“混合”方法采用二维或三维自一致的数值代码来描述所有物质（电子、离子、激发态和基态中性）和所有相互作用（弹性和非弹性碰撞、辐射的发射和吸收、与壁的相互作用）的行为。“集中”的方法讨论了专门的模型，这些模型只包含最重要的相互作用，降低了维度，或者只代表了排放的一部分。通过模型与实验的比较，揭示了放电的确切作用机理。
