The creation of Electromagnetic Waves is rooted in a genuine pedagogical problem. In the preface of the book, Shevgaonkar describes how, during his own student days, electromagnetics was often taught in a way that made it feel like nothing more than a "vector calculus course". He observed that many students lose interest because the subject seems purely mathematical and disconnected from the rest of their engineering curriculum, often being perceived as a "formula substitution exercise".
