Краткое описание

The energy flow caused by single particles is examined to form a physically based understanding for extinction and the electromagnetic optical theorem. The behavior of the energy flow is explained in terms of wave interference. The optical theorem is shown to be a relationship based on the relative phase between the wave incident on a particle and the wave scattered by it. The relative phase is determined by the refractive and absorptive properties of the particle and reveals how extinction depends on both scattering and absorption.
