This work is based on a series of university course lectures by a leading name in the field, and thoroughly covers the physics of the fourth state of matter. The book looks at non-relativistic, fully ionized, non-degenerate, quasi-neutral, and weakly coupled plasma. Intended for the student market, the text provides a concise and cohesive introduction to plasma physics theory, and offers a solid foundation for students wishing to take higher level courses in plasma physics.

This work contains over 80 exercises - carefully selected for their pedagogical value - with fully worked out solutions available in a separate solutions manual for professors. The author provides an in-depth dicussion of the various fluid theories typically used in plasma physics. The material presents a number of applications, and works through specific topics including basic plasma parameters, the theory of charged particle motion in inhomogeneous electromagnetic fields, plasma fluid theory, electromagnetic waves in cold plasmas, electromagnetic wave propagation through inhomogeneous plasmas, magnetohydrodynamical fluid theory, and kinetic theory.
