The author describes analytic and numerical methods, providing powerful and sophisticated solutions to electromagnetic problems. This book offers a thorough treatment of waves in planarly layered mediathe most studied of the inhomogeneous media. Spectral Representations of Sources. A Source on Top of a Layered Medium. The main idea of the method is that electromagnetic waves in weakly anisotropic media preserve their transverse structure as they do in isotropic media. Asymptotic W. C.

Michielssen, wave propagation behaviors and computational techniques for waves in inhomogeneous media. and sophisticated analytic and numerical WAVES IN INHOMOGENEOUS ISOTROPIC MEDIA by CHRISTOPHER ROBERT JAMES, University of British Columbia,0 A THESIS SUBMITTED IN When a plane P or S wave impinges on an interface between two homogeneous media, both reflected and transmitted waves are generated of the same wave type and with conversion. The boundary conditions that have to be satisfied by the wave field are the continuity of displacement and traction to ensure welded contact between the two half The quasi-isotropic approximation (QIA) of geometrical optics is outlined. Blending theory and analytical techniques in It is a comprehensive text which covers fundamental wave propagation behaviours and computational techniques for waves in inhomogenous media. A Source Embedded in a Layered Medium. The author describes powerful. These problems are presented as realistic models of actual situations which assumptions assure that monochromatic solutions of the wave equations have physical meaning and that the sound field of the localized source vanishes at infinityWave Equation for Nonstationary (Nonsteady-State) Moving Media The wave equation for free (not related directly to sources) sound waves was considered in [Ref., Chap] Waves and Fields in Inhomogeneous Media Weng Cho Chew Snippet viewWaves and Fields in Inhomogeneous Media Weng Cho Chew No preview available Our approach is general and treats the fieldsExpand One-Dimensional Planar InhomogeneityDerivation of the Scalar Wave EquationsReflection from a Half-SpaceReflection and Transmission in a Multilayered MediumRicatti Equation for Reflection CoefficientsSpecific Inhomogeneous Profiles It is a comprehensive text which covers fundamental wave propagation behaviours and computational techniques for waves in inhomogenous media.

Advantages of the QIA are illustrated by considering electromagnetic wave propagation in plasma, a number of optical problems * Variational methods for the scalar wave equation and the electromagnetic wave equation * Mode-matching techniques for inhomogeneous media * The Dyadic Green's function and its role in simplifying problem-solving in inhomogeneous media * Integral equation formulations and inverse problems * Time domain techniques for inhomogeneous media Covering basic theory at an engineering level, Waves and fields in Inhomogeneous Media emphasises the use of practical, analytical, and numerical computer techniques and mathematical methods and the selection of the best technique for a specific application. Classical analytic methods for one-dimensional inhomogeneity are described while A formalism based on dyadic Green functions is applied to the reflection and transmission of fields generated in the presence of anisotropic media.
