Providing a comprehensive overview of the radiative behavior and properties of materials, this book describes the physics of radiative transfer, methods for developing analysis, and various mathematical and numerical techniques. The fifth edition of this classic textbook includes four new chapters on inverse methods, electromagnetic theory, scattering, and absorption by particles, and near-field radiative transfer. Maintaining the fundamentals of the original, with chapter-end homework problems and other useful features, this new edition continues its tradition of serving both as a comprehensive textbook for those studying radiative transfer, and a repository of vital literary references for the serious researcher.
