Wave Scattering by Time-Dependent Perturbations An Introduction [Hardcover]

This book offers the first comprehensive introduction to wave scattering in nonstationary materials. G. F. Roach's aim is to provide an accessible, self-contained resource for newcomers to this important field of research that has applications across a broad range of areas, including radar, sonar, diagnostics in engineering and manufacturing, geophysical prospecting, and ultrasonic medicine such as sonograms.

New methods in recent years have been developed to assess the structure and properties of materials and surfaces. When light, sound, or some other wave energy is directed at the material in question, imperfections in the resulting echo can reveal a tremendous amount of valuable diagnostic information. The mathematics behind such analysis is sophisticated and complex. However, while problems involving stationary materials are quite well understood, there is still much to learn about those in which the material is moving or changes over time. These so-called non-autonomous problems are the subject of this fascinating book. Roach develops practical strategies, techniques, and solutions for mathematicians and applied scientists working in or seeking entry into the field of modern scattering theory and its applications.

Wave Scattering by Time-Dependent Perturbationsis destined to become a classic in this rapidly evolving area of inquiry.

G. F. Roachis professor emeritus of mathematics at the University of Strathclyde. His books includeAn Introduction to Linear and Nonlinear Scattering TheoryandGreen's Functions. This book by Roach is clearly written and covers a vast amount of material in a formal manner. As such, the book nicely complements the author's earlier book in the area and can be recommended to anyone interested in an introduction to this important area of applied mathematics. ---David L.
