ABSTRACT
In this chapter, Maxwell’s theory is briefly reviewed. In particular, it is shown that electromagnetic fields exist and they propagate in space as waves. Historically, the set of Maxwell’s equations were not all derived by Maxwell; they were attributed to him because, among other things, he correctly added a displacement current term to Faraday’s equation, and predicted the existence of electromagnetic waves from the set of equations that is now known as Maxwell’s equations [2,10,11].
