1.3.2 Strongly coupled complex (dusty) plasmas

When the Coulomb coupling parameter (Г) is greater than the unity (Г > 1), then the plasma is known as strongly coupled (nonideal) complex plasmas. For weak-to-intermediate Coulomb coupling (Г) values, the SCCDPS can have structure of liquids, and structure of solids for higher values of Г. Furthermore, SCCDPS are the collection of free microparticles that interact with each other with a strong Coulomb repulsion force and have structure at microscopic scale for the arrangement of particles. The particle motion in SCCDPS resembles that in the liquids or solids, and particles remain in relative fixed positions with respect to neighboring particles because of the strong Coulomb interactions present between the charged particles [7]. In SCCDPS, the Coulomb interaction P.E is much larger than the K.E of nearby particles.
