Abstract
In this chapter, a brief introduction to electrodynamics is first provided to review the theoretical basis how electromagnetic waves are modified in magnitude and direction as they propagate through different media. It is then demonstrated that Maxwell’s equations are of great utility for quantifying the radiative properties of particle scattering and absorption. The second half of the chapter is devoted to a short summary of geometrical optics. Geometrical optics, although a simple, empirical framework of ray tracing predating Maxwell’s theory, is also useful in satellite observations for characterizing the emission and reflection of radiation at the earth’s surface.
