Elementary Electromagnetic Phenomena
All the effects discussed in this text rely on the presence of electric, magnetic or electro-magnetic fields in the system. It is therefore natural to discuss first the governing equations and some basic electromagnetic phenomena. In this regard, “elementary” in the title of this chapter refers to subjects related to beam-wave interaction and not necessarily to undergraduate-level topics though a few really elementary concepts are discussed in Sects. 2.1 and 2.2.
