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: Wave propagation in multi (n- )- mode inhomogeneous media, quite generally is described by an n:th order wave equation with variable coefficients, or sometimes, especially in the case of 4-mode systems, by coupled, second order wave equations in total fields. It is shown how the propagation phenomena can be analyzed in terms of first order, coupled mode amplitude equations. These first order equations become especially simple when the system has symmetric, or anti-symmetric properties. Since the methods developed are completely general, they can be applied to a multitude of wave propagation phenomena, involving coupling between waves of very different physical nature. (Author).

This book was released on 1966 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The multi-mode wave equation is broken up in first order coupled wave equations, which are made use of to determine the interaction between electron cyclotron and whistler modes in passive and 'active', i.e. amplifying, barriers. The total energy flow, electro-magnetic and kinetic, can be expressed simply as a Poynting flux in terms of 'reduced' electric (and magnetic) fields. These fields, which are related to the original ones by generalized WKB-type amplitude coefficients, are the quantities to be analytically continued through the barriers. This continuation makes it possible to evaluate, for example, the magnitude of the whistler mode amplification of the system. (Author).

Download or read book Multi-mode Wave Coupling in Inhomogeneous Anisotropic Media written by Olof E. H. Rydbeck and published by . This book was released on 1967 with total page 287 pages. 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.

Book excerpt: International Series of Monographs in Electromagnetic Waves, Volume 11: Electromagnetic Wave Theory, Part 1 covers the proceedings of an International Scientific Radio Union (U.R.S.I.) Symposium on Electromagnetic Wave Theory. The book contains 61 chapters that are organized into three sections. The first section presents papers about wave propagation, which includes lateral waves; terrestrial waveguides; and plane waves in dissipative media. Next, the title reviews studies about wave guides, including basic properties of periodic waveguides; theoretical investigation of non-uniform waveguides; and waves in a coaxial line partially filled with plasma. The last section covers topics about surface waves, such as a dielectric prism in the corner of overmoded waveguide; lasers and optical communication systems; and microwave and laser resonators. The text will be of great use to researchers and practitioners of disciplines that study or utilize electromagnetic wave technologies, such as electrotechnics and electrical engineering.
