ABSTRACT
This chapter presents in a nutshell the fundamental aspects of engineering electromagnetics from the view of looking back in a reflective fashion at what has already been learned in undergraduate electromagnetics courses as a novice. It examines the approach of beginning with Maxwell’s equations and treating the different categories of fields as solutions to Maxwell’s equations. Judging from the contents of the vast collection of undergraduate textbooks on electromagnetics, there is definitely a heavy tilt toward the traditional, or historical, approach of beginning with statics and culminating in Maxwell’s equations, with perhaps an introduction to waves. Together with the constitutive relations, Maxwell’s equations form the basis for the entire electromagnetic field theory. The chapter considers the time variations of the fields to be arbitrary and introduce these equations and an auxiliary equation in the time domain form.
