This is easily one of the best EMI books I've ever read. It's main strength is its focus on PCB design which is after all the root cause of most EMI issues. The author does a great job of concisely and clearly explaining the topic, esp IO filtering. (Most EMI books are frankly too long; have way too much math; and cover too much material for the reader to absorb.) Especially illuminating is his explanation that current, NOT voltage, causes emissions.

My only complaint with this this book is that it does not differentiate enough between magnetic and electric fields. I.e., EM fields with a high impedance (E/H) are mainly electric fields and shielding (low impedance) works due to reflection from the impedance mismatch. EM fields with a low impedance are mainly magnetic fields so there is NOT much reflection (so absorption is needed instead which requires thick shielding). Also for digital boards, burying clock lines between reference planes works because the magnetic fields from the return currents cancels out from both planes, NOT due to shielding- so I don't agree with his assertion that guard traces help with EMI.
