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 presents the development of electromagnetic theory in the field of scattering for a wide range of objects. The solutions to several applied problems of electromagnetic wave scattering are presented including resonant electromagnetic wave scattering, solved by the integral equation method, and 2D and 3D scattering problems, solved by the asymptotical (short wave) method. Worked examples are provided throughout the text.
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 main audience for this book includes researchers in the field of electromagnetic scattering.
