Textbook in PDF format It is a great pity, I think, that so few students and professionals trained in the laws of applied electromagnetics understand the intimate linkage between those laws to which they have dedicated their lives and the principles of special relativity. Most of us are taught — if we learn about special relativity at all — that Einstein conceived of special relativity simply by imagining what it would be like to travel alongside a beam of light, concluding that nothing could move faster and that therefore the definitions of space and time needed revision. Even as an undergraduate, I remember wondering what makes light so special ? Why not the speed of sound, or the speed of particle radiation ? It surely isn’t that light is fast. Many things are fast, from our human perspective, which in itself is pretty meaningless on a cosmic scale. Why not hold up something incredibly slow and then say that nothing can move slower ? No, there had to be something about light, something unique to warrant granting it that special place as the universal governor of relative speed. In fact, Einstein had great reasons for holding light — electromagnetic waves — in such high regard. Those reasons are woven, directly and inextricably, into Maxwell’s equations. This book will explain why. For reasons that I hope I have explained, this book is targeted for engineering students and practicing engineering professionals, not theoretical physicists (who already have plenty of books on the subject available to them). Topics: Classical Electromagnetics, Reference Frame Transformation, Covariant Electrodynamics, The Calculus of Spacetime, Interactions with Matter, Guided Waves, Network Analysis
