We first consider scattering by a single particle. This chapter and the next discuss and derive the scattering characteristics of a single particle. Both exact and solutions are studied. Scattering by a single particle is an important subject in electromagnetics and optics. There exist several excellent textbooks on this subject van de Hulst 1957 Kerker 1969 Bohren and Huffman 1983 . We will treat those topics that are pertinent to later chapters of multiple scattering by random discrete scatterers. 1 Basic Scattering Parameters Scattering Amplitudes and Cross Sections Consider an electromagnetic plane wave impinging upon a particle which has permittivity ep r that is different from .
