Stop memorizing EMC rules of thumb. Start understanding why they work. Every design engineer has heard the folklore: keep traces short, add a ground plane, try a bigger capacitor, clip on a ferrite. It works, until it doesn't, and you're staring down a failed compliance test with no idea why the "standard fix" didn't fix anything.
The Electromagnetic Compatibility Engineering Handbook takes a different approach. Instead of eighteen disconnected topics and a grab-bag of tricks, it builds EMC from Maxwell's equations up, and shows you, chapter after chapter, that shielding effectiveness, filter insertion loss, cable coupling, and immunity performance are all the same physics, just applied at a different scale. Understand the principle once, and you can diagnose the problem you've never seen before, not just the one from the textbook.
