Electromagnetic wave scattering is the reradiation of electromagnetic energy which occurs when an electromagnetic field encounters an abrupt change in electrical or magnetic properties. This occurs when an electromagnetic field is incident on a structure or scattering object. When the original electromagnetic field crosses the boundary between two regions, each with different electrical or magnetic parameters, the field will change as it enters the second region. This abruptly changing propagation medium induces sources of scattering at the boundary between the two media, including conduction and displacement currents.

This book explores the development of electromagnetic theory in the field of scattering. Solutions to applied problems of electromagnetic wave scattering are presented and include resonant electromagnetic wave scattering, solved by the integral equation method, and 2D and 3D scattering problems, solved by the asymptotical (short wave) method. The book provides worked examples throughout for analysis of the electromagnetic wave scattering processes by different objects.

Demonstrations on how to obtain practically important estimates of scattering characteristics of objects are included. The book also includes tools to design new variants of the objects and entities are also provided.

The key audience for this book includes researchers in the field of electromagnetic scattering and designers of radar and radio equipment.
