  This chapter contains a short discussion of some fundamental plasma
phenomena. In section 2 we introduce key plasma properties like
quasi-neutrality, shielding, particle transport processes and sheath formation.
In section 3 we describe the simplest plasma models: collective phenomena
(drifts) deduced from single-particle trajectories and fundamentals of plasma
fluid dynamics. The last section discusses wave phenomena in homogeneous,
unbounded, cold plasma.
