    This (rather extensive) chapter focuses on the most important effect that follows from the time-dependent Maxwell equations, namely the electromagnetic waves, at this stage avoiding a discussion of their origin, i.e. the radiation process – which will the subject of Chapters 8 and 10. The discussion starts from the simplest, plane waves in uniform and isotropic media, and then proceeds to nonuniform systems, bringing up such effects as reflection and refraction. Then we will discuss the so-called guided waves, propagating along various long transmission lines – such as coaxial cables, waveguides, and optical fibers. Finally, the end of the chapter is devoted to final-length fragments of such lines, serving as resonators, and to effects of energy dissipation in transmission lines and resonators.
