This book was released on 1964 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Boltzmann equation corresponding to an electromagnetic wave propagating in a magnetoactive plasma is solved by making a spherical harmonic expansion of the electron distribution function.

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).

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).

Available in PDF, EPUB and Kindle. Book excerpt: This paper explains the differences and the reasons for the differences which exist between the theory of the zone-transport system of continuous zone refining as presented by W. G. Pfann and T. Abe. The identity between the mathematical model used to describe the zone-transport system and one of the models used to describe the recently reported matter-transport system is noted. Nondimensional equations for the zone-transport system are presented and the difference between the limit of alpha in the zone-void and zonetransport systems, when L sub e = 0, is correlated.

Available in PDF, EPUB and Kindle. Book excerpt: Optimal energy distribution applied to a least mean square error criterion for PCM transmission is discussed. Comparisons are drawn between the optimized scheme and standard scheme for: (1) White Noise Channel (2) White Noise and Rayleigh Fading Channel. It is concluded that for few bit samples only small energy savings are attained. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Wheeler-Feynman absorber theory of radiation is reviewed. A proof is offered to show that a sum of advanced and retarded effects from the absorber can provide the origin of radiative reaction. This proof is different from and perhaps simpler than that of Wheeler and Feynman. From arguments of momentum and energy conservation the necessity of the absorber for the emission of radiation is demonstrated for three cases. (Author).

This book was released on 1965 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theory of hydromagnetic ionizing waves has been developed which is valid in the region in which gas pressure is negligible, compared with magnetic pressure. The theory takes into account the energy expended in partial ionization of the gas behind the wave. The usual high conductivity boundary condition behind the wave is not employed. The electric field in front of the wave is taken as a parameter. Results of this theory are compared with available experimental measurements, and show good agreement. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Ball lightning has until this time defied physical explanation. This report summarizes the requirements that must be satisfied by any valid theory, reviews and evaluates previous theories, and evaluates the new theory of Finkelstein and Rubenstein developed under an AFCRL-monitored grant. It is concluded that the latter theory is the only promising one to date but that even this theory needs to be modified. A modification is proposed which would remove the remaining objections and it is suggested that experiments rather than further theoretical development will constitute the next decisive step.
