Up-to-date and comprehensive, An Introduction to Nonlinear Plasma Physics describes the numerous nonlinear effects in plasmas that are confined in an external magnetic field. Because a magnetized plasma is rich in wave motions, many effects related to wave phenomena can be studied. This book focuses on wave phenomena in magnetized plasmas for this reason, but it also contains some new results associated with unmagnetized plasma. Using model equations and methods derived from various areas of science, from astrophysics to fluid mechanics to nonlinear optics, the book explores high- and low-frequency wave motions as well as nonlinear low-frequency wave phenomena, making it a useful tool that applies to many disciplines.
