The optical theory of light scattering by nonspherical particles is fundamental to remote sensing of the atmosphere and ocean, as well as to other areas of computational physics, astrophysics, the biomedical sciences, and electromagnetics. At present, many training programs in light scattering are woefully lacking. This book fills the void in existing research on light scattering and training, particularly in the case of large scattering particles, and provides a solid foundation on which future research can be based, including suggestions for further directions in the field. With the elucidation of the theoretical basis for light scattering (particularly within the framework of the physical-geometric optics method) and the demonstration of practical applications, this book will be invaluable for training future scientists in the discipline of light scattering, as well as for researchers and professionals using remote-sensing techniques to analyze the properties of the atmosphere and oceans, and in the area of biophotonics.
