Filamentation phenomenon is one of the most important outcomes of applying a strong magnetic field to low-pressure plasmas and dusty plasmas. In this article, the variation of filamentation phenomenon with neutral gas pressure and plasma density will be investigated using numerical simulations. It will be shown through these simulations how the formation of the filamentary patterns in the magnetized plasma results in a localized electric field structure that strongly contributes to the properties of the filamentary patterns. Based on the results of the simulations, a theoretical model is derived that relates the width of the filamentary patterns to the plasma density. The model has been successfully employed to predict the width of the patterns emerging in various simulations of the magnetized plasma.

不同放电参数下强磁化等离子体中丝状现象的变化

成丝现象是将强磁场应用于低压等离子体和尘埃等离子体的最重要结果之一。在本文中，将使用数值模拟研究成丝现象随中性气压和等离子体密度的变化。通过这些模拟，将展示在磁化等离子体中丝状图案的形成如何导致局部电场结构，该结构对丝状图案的特性有很大贡献。基于模拟结果，推导出了将丝状图案的宽度与等离子体密度相关联的理论模型。该模型已成功用于预测磁化等离子体的各种模拟中出现的图案的宽度。
