A guide to wave-field computational methods based on contrast source type of integral equations.
Forward and Inverse Scattering Algorithms Based on Contrast Source Integral Equations presents a text that examines wave-field computational methods based on contrast source type of integral equations and the computational implementation in wave-field based imaging methods. Written by a noted expert on the topic, the book provides a guide to efficient methods for calculating wave fields in a known inhomogeneous medium. The author provides a link between the fundamental scattering theory and its discrete counterpart and discusses the forward scattering problem based on the contrast-source integral equations.
The book fully describes the calculation of wave fields inside and outside a scattering object with general shape and material property and reviews the inverse scattering problem, in which material properties are resolved from wave-field measurements outside the scattering object. The theoretical approach is the inverse of the forward scattering problem that determines how radiation is scattered, based on the scattering object. This important book:
Provides a guide to the effects of scalar waves, acoustic waves and electromagnetic waves
Describes computer modeling in 1D, 2D and 3D models
Includes an online site for computer codes with adjustable configurations
The goal I set to myself is that every theoretical problem is formulated in such a way that all physical configurations are discretized in a uniform way. The associated computer code must be executed as quickly as possible with minimal storage requirements, while remaining user‐friendly. I consider it the most important requirement. Students should recognize the common thread running through the various Matlab codes. In this book, I organized a Matlab structure so that every code listing does not exceed the end of a page. The description of a Matlab function is paged as close as possible to the theoretical and numerical formulations, enabling easy comparison of the two formulations. Furthermore, the choice for Matlab facilitates a simple conversion to C and C++, also for calling Matlab from C or C++.
Written for students, researchers, and professionals, Forward and Inverse Scattering Algorithms Based on Contrast Source Integral Equations offers a guide to wave-field computational methods based on contrast source type of integral equations and the computational implementation in wave-field based imaging methods.
