Book Description
The propagation of electromagnetic waves in a horizontally stratified layer of gyrotropic medium is discussed. Derivation of a comprehensive representation for magneto-ionic coupling coefficients allows interpretation of the physical significance of the coupling. Introduction of an invariant quantity for an inhomogeneous medium becomes an important guide for numerical solutions of the wave equation. Numerical results of magneto-ionic coupling coefficients are presented. Based on region properties, characteristic wave types are defined: for the isotropic region, linearly polarized waves are used; for the anisotropic region, elliptically polarized waves generally are applied.

Book Description
In this work, rigorous electromagnetic theory is used to determine the nose-on radar cross section of a perfectly conducting cone of finite height. The end cap of the cone is assumed to be a segment of a s spherical surface with center at the apex of the cone. Numerical results have been obtained for a cone having a total apex angle of 30 degrees and for values of [kappa alpha] ranging from 0.0259 to 5.18, where [kappa]=2 [pi]/[lambda] and [alpha] is the radius of the base of the cone. Siegel's Rayleigh method and by using Keller's modified geometrical optics as well as with experimental results obtained by Keys. The comparisons are instructive below [kappa alpha] = 3.2, the apparent upper limit of validity of the present results -- p.[3].

Book Description
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).

The Application of a System of Fixed-rotating Vectors to Circuit Analysis and Synthesis
Author : Carl T. Case
Publisher :
Page : 22 pages
File Size : 45,64 MB
Release : 1965
Category : Dielectrics
ISBN :
Book Description
A system of fixed-rotating vectors can be used to study the impedance loci of functions of the first Foster form and of systems including negative impedance converters. Of particular interest in the field of dielectrics and biological membrane studies is a parallel RC network, where the dielectric of the capacitor is given by the Debye dispersion relations. Such a network also falls into the category of the first Foster form.

On the Relative Efficiencies of Context-free Grammar Recognizers
Author : T. V. Griffiths
Publisher :
Page : 22 pages
File Size : 34,58 MB
Release : 1965
Category : Algorithms
ISBN :
Book Description
A number of diverse recognition procedures that have been proposed for parsing sentences with respect to a context-free grammar are described in this paper by means of a common device. Each procedure is defined by giving an algorithm for obtaining a nondeterministic Turing Machine recognizer that is equivalent to a given context-free grammar. The formalization of the Turing Machine has been chosen to make possible particularly simple descriptions of the parsing procedures considered.
