A complex plasma is a plasma in which dust particulates of micron size are embedded. Dust particulates are negatively charged and strongly coupled, while plasma particles are weakly coupled. Collective behavior of a complex plasma has been studied analytically as well as computationally. Analytical study revealed the effect of dipole moment on the wake potential of a dust particulate placed in the ion flow. The magnetic field effect on dust particulates has been studied and the rotation of a dust particulate and a dust cluster is analyzed. Simulation revealed the formation of clustering of dust particulates confined in an electrostatic field.

复杂等离子体是其中嵌入微米尺寸的灰尘颗粒的等离子体。尘埃粒子带负电荷，耦合性强，而等离子体粒子耦合性弱。复杂等离子体的集体行为已被研究的解析以及计算。分析研究揭示了偶极矩对离子流中尘埃粒子尾流电位的影响。研究了磁场对尘埃粒子的影响，分析了尘埃粒子和尘埃团的旋转。模拟结果表明，粉尘颗粒在静电场作用下形成团簇。
