Available in PDF, EPUB and Kindle. Book excerpt: The general problem of the propagation of a plane harmonic electromagnetic wave through an ionized gas is considered, including collisions, some form of electron density distribution, and a magnetostatically induced anisotropy. The pres ent state of the art is examined first, includ ing an outline of the WKB approximation and a summary of electron density distributions for which complete wave theory solutions exist. Then, specific analytical solutions and appropriate numerical calculations are derived to evaluate the effect of the applied magnetic field on pro pagation. A detailed parametric investigation, several exemplary flight conditions, and a possi ble experimental shock-tube program are analyzed assuming a homogeneous plasma. Preliminary estimates of the effects of plasma inhomogenei ties and nonuniformities in the magnetic field on propagation are obtained. (Author).

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 Wave Propagation in a Non Maxwellian Magnetoactive Nonlinear Plasma written by Robert J. Papa and published by . This book was released on 1966 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expressions for the components of a nonlinear ac conductivity tensor have been derived - corresponding to a temperate, weakly ionized, lossy magnetoplsma. The electrical conductivity tensor is nonlinear because its components are functions of the isotropic part of the electron velocity distribution function f, where f depends upon the amplitude and polarization of the local rf field By diagonalizing the conductivity tensor and referring Maxwell's field equations to the principal co-ordinate directions, it is shown that an elliptically polarized em wave normally incident upon an inhomogeneous magnetoplasma slab will launch only a right-hand and left-hand wave into the plasma if both the dc magnetic field and the electron density gradients are perpendicular to the interfaces. The net reflection transmission coefficients for left-hand and right-hand modes are computed using a Runge-Kutta numerical integration procedure. For low power levels, the right-hand and left-hand waves propagate independently of one another. For high field intensities, the propagation of the right-hand mode depends upon the amplitude of the left-hand mode, and vice versa. Reflection and transmission coefficients are presented as a function of normalized plasma parameters. (Author).
Download or read book Plasma Physics In Active Wave Ionosphere Interaction written by Spencer P Kuo and published by World Scientific. This book was released on 2017-11-29 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: One essential feature of plasma media is supporting various plasma waves and dictating electromagnetic wave propagation. This textbook provides students with an understanding of plasma waves, which is key to theoretical and experimental plasma research and understanding the experimental results, and will enable them to expand their studies into related areas.The first part of the text provides the basis of plasma modes, including the formulations, analyses and the physical characterizations. The second part introduces techniques for the studies of wave propagation in inhomogeneous plasma and of nonlinear mode-mode coupling in turbulent plasma as well as in active plasma, applied to exemplify the excitation of parametric instabilities in high-frequency (HF) wave heated ionospheric plasma. The third part introduces nonlinear plasma waves of periodic function forms and of solitary forms; a potential application of the HF wave-ionosphere interaction for setting up an ionospheric very-low-frequency transmitter for underwater communications is introduced.This is also a useful reference book for researchers in the areas of plasma physics and engineering, and in geophysics.
Download or read book Electromagnetic Fluctuations In Plasma written by A Sitenko and published by Elsevier. This book was released on 2012-12-02 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic Fluctuations in Plasma focuses on the theoretical investigation of the electromagnetic properties of a plasma (an ionized gas). The manuscript first takes a look at the general theory of fluctuations and electromagnetic fluctuations in media with space-time dispersion. Discussions focus on spectral distribution of the fluctuations and energy dissipation in the medium; dielectric and magnetic permittivities in a medium with spatial dispersion; current, charge, and field fluctuations in a medium; and inversion of the fluctuation-dissipation theorem. The text then examines the electrodynamic properties of an electron plasma and electromagnetic fluctuations in an electron plasma. The publication ponders on fluctuations in an electron-ion plasma and electron plasma in a magnetic field. Topics include plasma dielectric permittivity tensor in a magnetic field; longitudinal plasma oscillations in a magnetic field; fluctuations in charge and current densities in an equilibrium electron-ion plasma; and electron and ion density fluctuations in an equilibrium plasma. The text also tackles the passage of charged particles through plasma and dynamic friction and diffusion coefficients in a plasma. The book is a dependable reference for readers interested in the study of the electromagnetic properties of a plasma.

Download or read book Nonlinear Electromagnetic Wave Propagation in Plasmas written by Robert J. Papa and published by . This book was released on 1966 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review is presented of the current literature pertaining to high power rf field-plasma interactions. In the survey, the class of nonlinear interactions is restricted to the case where the effective dielectric constant of the plasma is a function of the local electric field intensity. Since the propagation characteristics of an em wave depend upon the effective dielectric constant, the presence of an intense rf field can modify the propagation characteristics of an em wave. The assumptions and basic theoretical approach of each author are discussed and the most significant results are summarized. The approaches used by different authors are compared. A critique is made of the various appraches and their advantages and limitations are pointed out. (Author).

This book was released on 2013-03-09 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main part of the book describes the behaviour of a charged particle in an electromagnetic field, and the electrodynamics of plasmas, liquid crystals and superconductors. These very different subjects have an important common feature, namely the fundamental role played by the magnetic field. Plasmas, liquid crystals and superconductors can be considered as magnetoactive media, because their electromagnetic characteristics are strongly affected by an external magnetic field.
