1.3.1 Weakly coupled complex (dusty) plasmas

For weakly coupled complex (dusty) plasmas (WCCDPS), the Coulomb coupling parameter (Г) is less than the unity (Г < 1), and it also called the weakly coupled ideal plasmas because Columbic collisions are negligible. Weakly coupled plasmas, like a gas, have no structure because Coulombic interactions are negligible between the particles and particle motion is like molecular motion in gases and particles have nearly random positions with respect to nearest neighbors [7]. For WCCDPS, the K.E (thermal energy) is much larger than the Coulomb interparticle P.E of nearest particles.
