Abstract
This set of lecture notes was prepared for a single-semester junior-level course on the fundamentals of electromagnetic wave phenomena offered in the Elmore Family School of Electrical and Computer Engineering at Purdue University. The class serves as a follow-up to a first course on electromagnetic physics that primarily covers electrostatics and magnetostatics, with a little time spent discussing the very basics of plane waves. The second course on electromagnetic waves covers a wide range of topics, beginning from time-varying Maxwell’s equations and then developing in depth the fundamentals of plane waves. After that, phenomena related to transmission lines is covered in detail before discussing the field theory treatment of waveguides and resonators. The course concludes by discussing the basics of antenna theory. Throughout the lecture notes, the material is often related to important modern technologies and applications to reinforce the key role that electromagnetic waves play in our lives.
