Theory of loaded scatterers
WebbWhile the problem of the multiple scattering of particles by a random distribution of scatterers has been treated classically through the use of the Boltzmann integro-differential equation, the corresponding problem of the multiple scattering of waves seems to have received scant attention. All previous treatments have considered the problem in … WebbRather than developing and presenting a formal theoretical foundation of electromagnetic theory, this book instead focuses on various aspects of EM radiation from a variety of perspectives. The goal is to provide the reader with computational tools for determining quantitatively why and where radiation is emitted by antennas and scatterers.
