Book excerpt: Excerpt from Wave Propagation in a Plasma Based on the Cold Plasma Model The study of wave propagation originated decades ago with the examination of radio wave propagation in the ionosphere. Once the cold plasma conductivity tensor is developed, the problem reduces to a study of Maxwell's equations with the specified conductivity tensor. By far, the bulk of the work done in this field has been based on geometric optics or plane stratified medium approximations. Neither of these approximations is particularly valid in many typical laboratory plasma applications at moderately low frequencies and moderately long wavelengths. Additionally, the appearance of resonances and the associated plasma heating brings into question the relevance of the simple cold plasma model. Here, we intend to examine fairly generally the consequences of the cold plasma model for wave propagation problems. We intend to compare the situation in a plasma with the better known problems of scattering of waves in electromagnetic theory or in quantum mechanics. Our attack on this problem is based on an examination of the system of partial differential equations that defines the wave propagation problem. We will not be able to give definitive answers to many of the questions we raise, as the problems appear far beyond current knowledge. We will show that waves in plasmas behave, in many cases, quite unlike the much simpler version of waves in ordinary electromagnetic theory or in quantum mechanics. We believe that the questions we raise must be addressed directly to obtain reliable, quantitative measures of ion cyclotron or lower hybrid wave heating and model patterns in a plasma device. Any direct numerical calculations face immediately the problems posed here. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: The book aims to present current knowledge concerning the propagation of electro magnetic waves in a homogeneous magnetoplasma for which temperature effects are unimportant. It places roughly equal emphasis on the radio and the . hydromagnetic parts of the electromagnetic spectrum. The dispersion properties of a magnetoplasma are treated as a function both of wave frequency (assumed real) and of ionization density. However, there is little discussion of propagation in a stratified medium, for of collisions is included only which reference may be made to Budden [1] . The effect in so far as this can be done with simplicity. The book describes how pulses are radiated from both small and large antennas embedded in a homogeneous magneto plasma. The power density radiated from a type of dipole antenna is studied as a function of direction of radiation in all bands of wave frequency. Input reactance is not treated, but the dependence of radiation resistance on wave frequency is described for the entire electromagnetic spectrum. Also described is the relation between beaming and guidance for Alfven waves.
Download or read book Plasma Waves in the Magnetosphere written by A.D.M. Walker and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a study of plasma waves which are observed in the earth's magnetosphere. The emphasis is on a thorough, but concise, treatment of the necessary theory and the use of this theory to understand the manifold varieties of waves which are observed by ground-based instruments and by satellites. We restrict our treatment to waves with wavelengths short compared with the spatial scales of the background plasma in the mag netosphere. By so doing we exclude large scale magnetohydrodynamic phenomena such as ULF pulsations in the Pc2-5 ranges. The field is an active one and we cannot hope to discuss every wave phenomenon ever observed in the magnetosphere! We try instead to give a good treatment of phenomena which are well understood, and which illustrate as many different parts of the theory as possible. It is thus hoped to put the reader in a position to understand the current literature. The treatment is aimed at a beginning graduate student in the field but it is hoped that it will also be of use as a reference to established workers. A knowledge of electromagnetic theory and some elementary plasma physics is assumed. The mathematical background required in cludes a knowledge of vector calculus, linear algebra, and Fourier trans form theory encountered in standard undergraduate physics curricula. A reasonable acquaintance with the theory of functions of a complex vari able including contour integration and the residue theorem is assumed.
Download or read book Plasma Waves written by D.G. Swanson and published by Elsevier. This book was released on 2012-12-02 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma Waves discusses the basic development and equations for the many aspects of plasma waves. The book is organized into two major parts, examining both linear and nonlinear plasma waves in the eight chapters it encompasses. After briefly discussing the properties and applications of plasma wave, the book goes on examining the wave types in a cold, magnetized plasma and the general forms of the dispersion relation that characterize the waves and label the various types of solutions. Chapters 3 and 4 analyze the acoustic phenomena through the fluid model of plasma and the kinetic effects. These chapters also describe the averaging process for the fluid element motion using expanded Boltzmann equation for each species in a velocity moment expansion, truncating the expansion at some suitable level, depending on the particular problem. The remaining four chapters discuss the effects of adding sharp boundaries, slowly varying inhomogeneities, nonlinearities at several levels, and turbulent plasmas. Supplementary texts on complex variables and the special functions in plasma physics are provided in the concluding section of this text. The book is an advanced text for graduate students who have had an introductory plasma course at some level.

David DeVorkin, Sky & Telescope Virginia Trimble offers readers a fascinating and accessible tour of the stars. An astronomer with shared appointments in California and Maryland, the author ranges over a large portion of the universe as she discusses the search for life on other planets, how galaxies form, why stars explode and die, and the nature of the elusive dark matter in the universe. She also explains the astronomical significance of Cheeps' pyramid and leads the reader through scientific speculation about what and when the Star of Bethlehem might have been. Throughout, Trimble points to the exciting unanswered questions that still perplex the field and considers the formidable tasks to be faced by the next generation of young astronomers.
Download or read book Kinetic Theory of Plasma Waves written by Marco Brambilla and published by Oxford University Press. This book was released on 1998 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with the propagation and absorption of high frequency waves in plasmas. The text collects in a structured and self-contained way the basic knowledge on the broad and varied behavior of plasma waves, adopting the microscopic kinetic description of the plasma as unifying principle. The internal coherence of the theory is explicitly stressed, and interesting physical phenomena peculiar to plasmas are discussed in detail, including collisionless damping of waves, the development of stochasticity in the interactions of charged particles with electromagnetic waves, and nonlinear interactions between waves. The most common and useful approximations used in solving practical problems are derived as special cases from the more general kinetic approach, thereby clarifying their meaning and domain of applicability. This exposition should be useful to plasma physicists both as an introduction and a reference to this field of research.

Available in PDF, EPUB and Kindle. Book excerpt: The text presented here is an extended english version of a report by the authors which appeared in April 1983 at the Institute of Cosmical Research of the Academy of Sciences of the GDR in German. It covers several selected topics on nonlinear wave-plasma interactio,ll in a treatment based on a hydrodynamic plasma description. Thus, no attempt has been made to give a comprehensive view on all aspects of the interaction of strong electromagnetic waves with plasmas. The text is partly introductory and presents partly current results. The authors hope that it will be of interest to students and scientists not only in the field of plasma physics.

Download or read book Electromagnetic Wave Propagation in Anisotropic Plasmas Along the Direction of a Static Magnetic Field written by M. P. BACHYNSKI and published by . This book was released on 1964 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental and theoretical investigation of the propagation of electromagnetic waves in an anisotropic plasma along the direction of the applied static magnetic field was conducted. Experimental measurements of electron density and attenuation using circularly polarized waves (left-hand or right-hand) show good agreement with theory and with each other over all ranges of parameters. For the right-hand mode at radio frequencies above the electron cyclotron frequency, 'cut-off' occurs at much lower electron densities than in the absence of a magnetic field. For the left-hand wave, both the phase change and attenuation decrease with magnetic field and the wave is affected much less by the plasma than the right-hand wave over the range of parameters encountered in the experiments. The theory of propagation of a linearly polarized wave in a lossy anisotropic plasma was derived. Investigations of the collisional effects on e-m wave propagation in the region of the electron cyclotron frequency show a reversal in phase of the wave passing through the plasma as the electron density is increased. This phenomenon occurs only for the right-hand circularly polarized wave at frequencies very near but just above the electron cyclotron frequency. Collisional effects based on cold plasma theory can account for this behavior.
