Book Description
Expressions for the electromagnetic radiation from an electric dipole in an infinite cold anisotropic plasma are presented under the condition that the operatingfrequency is much less than the ion gyro frequency. It is found that the major portion of the radiation is concentrated along the direction of the magnetostatic field. (Author).

Book Description
The general solution to the problem of the radiation of an electric dipole in a magnetically-biased cold plasma is presented. Since the magnetostatic field causes the plasma to be anisotropic, the far field is in general quite complicated. It is found that in general several waves exist, traveling in different directions with different indices of refraction. These waves interfere to produce beats and amplitude modulation, also causing the resultant time-average energy flow to have components in other than the radial direction, a result which is contrary to the isotropic case.

Book Description
An investigation is described of radiation from an electric point dipole situated in a cold, collisionless, homogeneous, electronic plasma medium. Two limiting cases of a gyroelectric medium are studied. The magnetostatic biasing field is first taken to be equal to zero, making the medium isotropic, and then it is taken to be infinite, causing a uniaxial anisotropy. The retarded electromagnetic fields and the instantaneous and averaged values of irreversibly radiated power are calculated. In each medium, the partial differential equations resulting from the two-sided Laplace transformation of Maxwell's equations with an oscillating electric dipole source and the constitutive equations (derived from the appropriate form of the Lorentz force equation) are solved.

Book Description
In this book, various antennae in plasmas, particle beam antennae, phase, group and ray velocity surfaces of various plasma modes, RF ray trajectories and wave fronts in inhomogeneous anisotropic plasmas, plasma waveguides, radiations in ion beams and plasma streams, and useful kinetic plasma dielectric tensor are illustrated with many interesting new phenomena in anisotropic plasmas. Many theoretical and experimental results are demonstrated with clearly understandable figures. In addition to these fields, the properties of superconducting plasmas are also presented.Results from radiation phenomena in various schemes are shown and they can be applied in many fields, e.g., space (plasma) sciences, artificial satellites in space, RF heatings of plasmas, and advanced processing plasmas. Fundamental anisotropic phenomena in anisotropic plasmas are also expected to be applicable in other anisotropic media such as anisotropic optical fibers.

Book Description
An expression for the electric field produced by an arbitrarily oriented electric dipole in a warm, anisotropic, single-fluid plasma is derived. The radiation patterns are found for the specific example of a dipole oriented perpendicularly to the extermally impressed magnetic field, for a plasma in which omega sub p = 0.412 omega, omega sub c = 0.75 omega, omega = 3 x 10 to the 8th power radians per second, and U = 0.003 c. Results are found to be consistent with previous analyses, yet show significant changes produced by the consideration of electron temperature. Large maxima of radiation were found in the endfire direction, which are not found by the cold-plasma analysis. The procedure of analysis was to reduce the governing equations for this model to a single inhomogeneous wave equation in the electric field intensity, and to subsequently introduce a dyadic Green's function representation for the electric field intensity. The resulting homogeneous equation in the Green's function dyadic, was then Fourier-transformed, and the alebraic equations produced were then solved for the Green's function dyadic. One can, by a sixfold integration, find the field intensity due to any finite current configuration, using this result. (Author).

Book Description
Today many scientists recognize plasma as the key element to understanding new observations in near-Earth, interplanetary, interstellar, and intergalactic space; in stars, galaxies, and clusters of galaxies, and throughout the observable universe. Physics of the Plasma Universe, 2nd Edition is an update of observations made across the entire cosmic electromagnetic spectrum over the two decades since the publication of the first edition. It addresses paradigm changing discoveries made by telescopes, planetary probes, satellites, and radio and space telescopes. The contents are the result of the author's 37 years research at Livermore and Los Alamos National Laboratories, and the U.S. Department of Energy. This book covers topics such as the large-scale structure and the filamentary universe; the formation of magnetic fields and galaxies, active galactic nuclei and quasars, the origin and abundance of light elements, star formation and the evolution of solar systems, and cosmic rays. Chapters 8 and 9 are based on the research of Professor Gerrit Verschuur, and reinvestigation of the manifestation of interstellar neutral hydrogen filaments from radio astronomical observations are given. Using data from the Green Bank 100-m telescope (GBT) of the National Radio Astronomy Observatory (NRAO), detailed information is presented for a non-cosmological origin for the cosmic microwave background quadruple moment. This volume is aimed at graduate students and researchers active in the areas of cosmic plasmas and space science. The supercomputer and experimental work was carried out within university, National laboratory, Department of Energy, and supporting NASA facilities.
