ABSTRACT
Plasma is one of the four fundamental states of matter, being a conductive assembly of charged particles (electrons and ions), neutrals, and fields that exhibit collective effects. Plasmas carry electrical currents and generate magnetic fields. Plasmas are radically multiscale in at least two senses: (1) most plasma systems involve electrodynamic coupling across micro-, meso-, and macroscale and (2) plasma systems occur over most of the physically possible ranges in space, energy, and density scales.
