Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The report deals with coupled waves, or coupled modes in arbitrary inhomogeneous n-wave systems. The partial waves, which make up the total wave field (of some physical kind) are expressed either in terms of so called inhomogeneous wave numbers, or of regular homogeneous ones (with corresponding phase integrals). The partial wave amplitudes are related to each other by first order coupled amplitude equations, with coupling coefficients depending upon the physical nature of the modes appearing in the system. These wave couplings are formally simple only when the partial waves have symmetrical properties of some kind (which is the case in many practical applications). A great number of coupled mode systems are analysed, compared, and discussed in considerable detail, with applications for example to magnetoionic, and to active (amplifying), inhomogeneous media. This report represents a major effort to relate all coupled wave phenomena to each other, irrespective of their particular physical background; in short to present a unified theory of multi-mode couplings in inhomogeneous media.

Section A. on the Transformation of the Wave Equations of an Inhomogeneous Multi-wave System to Coupled Mode Form: Section B. on Inhomogeneous Wave Numbers for Longitudinal Propagation in a Magneto-ionic Medium written by Ake G. Hjalmarson and published by . This book was released on 1967 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: By means of matrix formalism any linearized form of wave equations in total fields, which govern the propagation in an inhomogeneous multi-mode system can be transformed to coupled mode form. Various types of mode definition and coupled mode equations are obtained. The nature and properties of a mode definition depend upon the choice of original wave equations in total fields. Furthermore the modes can be defined by means of 'homogeneous' and 'inhomogeneous' models. The physical interpretation of the mode representation is a very important part of a coupling theory. To illuminate this situation the case of longitudinal propagation in an inhomogeneous magneto-ionic is treated by means of homogeneous and inhomogeneous mode representations. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The performance of a plurality-count diversity combiner for fading M-ary transmissions is analyzed, and calculated error probabilities are presented graphically for alphabet sizes of 2, 8, and 32. The performance is shown to be within 3 dB of that of an optimum square-law combiner for moderate alphabet sizes when there is no restriction on the allowable number of diversity branches. It is shown that a worthwhile saving in transmitted power can be effected by using nonbinary alphabets with plurality-count combining for the transmission of binary data. The availability of extra information from the combiner for use with error-correction is discussed.

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).
