最近，我们已经报道了一个微波等离子体射流在大气中的氩气，能够在整个石英管内产生连续的流光放电，而几个分叉产量立即在石英管中的铜线的端部时，入射功率达到20 W。然而，放电的电离过程仍然不是很清楚。本文用蒙特卡罗碰撞方法对2D3V粒子在胞内的等离子体射流进行了数值研究。通过对不同时间步长的模拟结果进行采样，得到了等离子体和电磁场分布的详细信息。模拟结果表明，等离子体射流的产生归因于种子等离子体的表面等离子体激元的增强的电场触发及其与等离子体的相互作用。
Recently, we have reported a microwave plasma jet at atmosphere in argon, capable of generating filamentary streamer discharges within the entire quartz tube, while several bifurcations yield at the end of the copper wire immediately in the quartz tube when incident power reaches 20 W. However, the ionization process for the discharges is still not very well clarified. This paper shows a numerical study of the proposed plasma jet by means of the 2D3V particle in cell with Monte Carlo collision method. The detailed information about the distributions of plasmas and electromagnetic fields is obtained by sampling the simulated results at different time steps. The simulation results suggest that the production of the proposed plasma jet is attributed to the seed plasmas triggered by the enhanced electric field of surface plasmon polaritons and its interaction with plasmas.
