Book Description
Possibility of excitation of finite amplitude longitudinal waves in a collisionless and cold plasma in the presence of uniform magnetic field is demonstrated. Such waves are found to be anharmonic in shape, in contrast to the usual harmonic, that is, sinusoidal waves of the linear theory. These nonlinear plasma waves arise as a result of nonlinear motion and the dispersive nature of plasma media. The two competing processes, nonlinearity and dispersion in a moving plasma medium strike a balance to produce a quasi-steady state which can support finite amplitude waves. These waves are associated with large amplitude oscillating electric fields which may be responsible for coherent radio-to-microwave radiation from coronal plasma and particle acceleration during solar flares. The estimate of sporadic electromagnetic and particulate radiation is important for application to the solar flare patrol and the Air Force Communications System. (Author).

Book Description
This compact and well-organized text provides an introduction to plasma physics and shows the interaction of plasmas without any external magnetic fields. It deals with the concepts, processes, and characteristic features associated with plasmas. The interaction of magnetic fields on plasma is purposely excluded in this introductory text to help students grasp the basics first, which makes the understanding of the effects of the magnetic fields easier in the subsequent courses. The book begins with a review of the concepts of kinetic theory of gases, collision phenomena in ionized gases and motion of charged particles. It goes on to give a discussion on the characteristic properties of plasmas and conditions to be satisfied for an ionized gas to show plasma behaviour. In addition, the text covers such topics as transport processes, plasma oscillations, and plasma as a dielectric medium, as a charged fluid, and as a many-body system. Finally, it provides a systematic analysis of important instabilities for an unmagnetized plasma, as well as a discussion on the radiation processes. The organization is systematic and the style lucid, with more physical insight and only relevant mathematics. The text is well illustrated, and the References and Bibliography at the end of the book should stimulate those students who have a desire to study the subject deeper. It is a one-semester text and is designed for the undergraduate, postgraduate and research students of science and engineering who wish to choose plasma physics, astrophysics or space physics as their special areas of study.

Book Description
This volume contains two papers that review certain theoretical problems that have been studied in the Laboratory of Plasma Accelerators and Plasma Physics of the P. N. Lebedev Physics Institute of the Academy of Sciences of the USSR. The review of R. R. Kikvidze and A. A. Rukhadze, "Theory of oscillations and stability of a semiconductor plasma with low carrier density in a strong electric field," is devoted to a solid-state plasma. The main attention is devoted to the fact that in such a plasma electro magnetic waves are effectively generated if there is a negative current-voltage characteristic in the carrier current; this effect can compete in importance with the well-known Gunn effect. In their fundamental review paper "Nonlinear theory of the interaction of waves in a plasma," V. V. Pustovalov and V. P. SHin set forth the fundamentals of the theory of nonlinear interaction of waves in a hot rarefied plasma. Besides a systematic exposition of the pro cedure for deriving the equations that describe the nonlinear interaction of waves in an iso tropic or an anisotropic (magnetized) plasma, they study many concrete examples relating to the interaction of definite types of waves under different conditions.

Book Description
Nonlinear Wave and Plasma Structures in the Auroral and Subauroral Geospace presents a comprehensive examination of the self-consistent processes leading to multiscale electromagnetic and plasma structures in the magnetosphere and ionosphere near the plasmapause, particularly in the auroral and subauroral geospace. It utilizes simulations and a large number of relevant in situ measurements conducted by the most recent satellite missions, as well as ground-based optical and radar observations to verify the conclusions and analysis. Including several case studies of observations related to prominent geospacer events, the book also provides experimental and numerical results throughout the chapters to further enhance understanding of how the same physical mechanisms produce different phenomena at different regions of the near-Earth space environment. Additionally, the comprehensive description of mechanisms responsible for space weather effects will give readers a broad foundation of wave and particle processes in the near-Earth magnetosphere. As such, Nonlinear Wave and Plasma Structures in the Auroral and Subauroral Geospace Nonlinear Wave and Plasma Structures in the Auroral and Subauroral Geospace is a cutting-edge reference for space physicists looking to better understand plasma physics in geospace. - Presents a unified approach to wave and particle phenomena occurring in the auroral and subauroral geospace - Summarizes the most current theoretical concepts related to the generation of the large-scale electric field near the plasmapause by flows of hot plasma from the reconnection site - Includes case studies of the observations related to the most "famous events during the last 20 years as well as a large number of experimental and numerical results illustrated throughout the text
