ABSTRACT
This chapter presents that the effects of the Finite Size Particle (FSP) method, and examines how the real physics is modified by introducing the concept. It describes some applications to clarify the transition from the point-charge plasma to FSP plasma. The chapter shows how the charge density, field strength, force and potential are modified by introducing the FSP concept. In thermal equilibrium a plasma sustains fluctuations of various collective modes of oscillations. According to statistical mechanics, the probability of finding a certain energy level in a canonical ensemble is given by the Boltzmann distribution. A computer simulation would have obvious difficulty processing a large number of ions and electrons for a realistic plasma.
