This is the first book to unify the theories of acoustic, electromagnetic, and elastic waves and discuss the many physical and geometric aspects of their interactions with obstacles. It offers a complete introduction to scattering theory, and discusses low frequency scattering in particular. A significant number of results are previously unpublished, and this book fills many gaps in the existing literature. Included is an extended bibliography covering the whole existing literature on low frequency scattering, making this an invaluable reference for researchers.

This book addresses issues of scattering theory and biomedical engineering, as well as methodological approaches and tools from related scientific areas such as applied mathematics, mechanics, numerical analysis, and signal and image processing.
