Abstract
Because interstellar dust, or at least a major fraction of it, is in the form of solid particles with dimensions comparible to or less than optical wavelengths, an understanding of the detailed electromagnetic interactions of such particles is evidently required. In this chapter we consider the behaviour of particles of regular shapes, spheres, cylinders, as well as core—mantle concentric spheres. Spherical particles are considered to provide a satisfactory representation of randomly oriented irregular—shaped interstellar grains, whereas the properties of infinite cylinders are taken to represent the polarising behaviour of elongated partially aligned grains. Core—mantle spheres provide a model for grains which have acquired mantles of materials other than the cores. If the core is replaced by a vacuum cavity we also have a representation for hollow interstellar grains.
