Download or read book Low and High Frequency Asymptotics written by V.K. Varadan and published by Elsevier. This book was released on 2013-10-22 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on asymptotic methods in the low and high frequency limits for the solution of scattering and propagation problems. Each chapter is pedagogical in nature, starting with the basic foundations and ending with practical applications. For example, using the Geometrical Theory of Diffraction, the canonical problem of edge diffraction is first solved and then used in solving the problem of diffraction by a finite crack. In recent times, the crack problem has been of much interest for its applications to Non-Destructive Evaluation (NDE) of flaws in structural materials.

Download or read book Handbook of Radiation and Scattering of Waves written by Adrianus T. de Hoop and published by . This book was released on 1995-01-01 with total page 1085 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Radiation and Scattering of Waves is a self-contained, medium-level handbook on the time-domain and complex frequency domain radiation and scattering of elastic waves in solids, electromagnetic waves and acoustic waves in fluids. The emphasis is placed on reciprocity as a basic concept for developing the methodology of handling forward (direct) and inverse sources and scattering problems. Using international nomenclature, the text presents a consistent use of the subscript notation for vectors and tensors enabling an effortless transcription of the mathematical expressions into statements in any high-level programming language (i.e., FORTRAN 77 or FORTRAN 90) or in symbolic manipulation programs such as Mathematica (r). Carefully selected exercises, with answers, are provided at the end of each section. This handbook assumes the reader has a knowledge of elementary mechanics and differential calculus, as well as a grasp of Laplace and Fourier transformation methods. Displays a consistent use of vectors and tensors Covers time domain analysis Covers fundamentals of elastic wave motion in solids Explains derivation of the basic equations of elastodynamics Develops time-domain methods side-by-side with complex frequency domain methods Facilitates easy transcription of mathematical expressions into statements in any high-level programming language such as FORTRAN 77 or FORTRAN 99, or in symbolic manipulation programs like Mathematica(r) through consistent use of subscript notation for vectors and tensors

Available in PDF, EPUB and Kindle. Book excerpt: In this article we present a multiple scattering analysis of the coherent wave propagation through an inhomogeneous medium consisting of either random or periodic distribution of scatterers of arbitrary shape. Both specific and random orientations of the scatterers are considered. The mathematical unity inherently present in the T-matrix formalism for the three wave fields, namely acoustic, electromagnetic and elastic, is employed in conjunction with suitable averaging procedures to formulate a self-consistent multiple scattering theory. For a random distribution of scatterers we use a configurational averaging procedure, while for a periodic distribution, we use a suitable lattice sum based on crystallographic theory. The information about the orientation of the scatterers has been incorporated into the T-matrix of the scatterer itself thus making formalism a convenient computational scheme to study the anisotropic effects in an inhomogeneous medium. The statistically averaged equations obtained by the analysis are then solved by using Lax's quasicrystalline approximation to obtain the bulk or effective properties of the medium. Numerical results are presented for propagation speeds, attenuation and frequency dependent elastic properties for a range of frequencies to demonstrate the broad applicability of the T-matrix method.

Available in PDF, EPUB and Kindle. Book excerpt: The inverse scattering problem is central to many areas of science and technology such as radar, sonar, medical imaging, geophysical exploration and nondestructive testing. This book is devoted to the mathematical and numerical analysis of the inverse scattering problem for acoustic and electromagnetic waves. In this fourth edition, a number of significant additions have been made including a new chapter on transmission eigenvalues and a new section on the impedance boundary condition where particular attention has been made to the generalized impedance boundary condition and to nonlocal impedance boundary conditions. Brief discussions on the generalized linear sampling method, the method of recursive linearization, anisotropic media and the use of target signatures in inverse scattering theory have also been added.
