Handbook of Electromagnetic Compatibility Engineering: A Practical Guide for Electronics Designers to Master EMI Control, Shielding, and Grounding

A design can be elegant, efficient, and perfect on the bench — and still fail the day it reaches the compliance lab. A return current takes the wrong path, a cable shield is terminated with a pigtail, an enclosure seam radiates like an antenna, and a product that worked yesterday is suddenly over the limit line. For many electronics engineers, electromagnetic compatibility is the part of the job that feels like a black art. The physics was taught abstractly, the standards read like law, and the usual advice arrives as disconnected rules of thumb that fail the moment conditions change. Fixing these problems late — after the layout is frozen and the schedule is set — is where budgets and deadlines quietly disappear. This comprehensive, practical handbook closes the gap between electromagnetic theory and the decisions that determine whether a product ships. Every principle is developed from first principles and carried through to a design rule you can apply, a number you can compute, and the limit your product must meet. Instead of memorising recipes, you learn to follow the signal — from a switching edge, through the coupling paths that turn it into interference, out past the shields and filters meant to contain it, to the antenna and receiver that measure it. With this guide you can: trace any emissions or immunity problem to its source using a single source–path–victim method; predict which coupling mechanism dominates, and at what frequency, before you build; design grounding, bonding, and return paths that control noise instead of creating it; apply shielding, filtering, ferrites, and transient protection with an understanding of what really limits each; lay out a circuit board so emissions are prevented at the source, not chased afterward; protect inputs and enclosures against electrostatic discharge and fast transients; and run pre-compliance checks and reason from a failing result to a fix. Key topics: field and frequency-domain fundamentals; the four coupling mechanisms; common- and differential-mode current; grounding and shielding; cables and transfer impedance; filtering and surge suppression; board design and signal integrity; electrostatic discharge; system- and enclosure-level control; standards and measurement; and worked troubleshooting case studies with answer keys. Written for practising electronics and hardware design engineers, board and layout designers, product, systems, compliance, and test engineers — and for advanced students moving from theory into real design. It assumes comfort with circuit theory and basic electromagnetics, but no prior time in a test chamber. Get your copy and turn electromagnetic compatibility from a source of late surprises into a discipline you can design with from the very first schematic.
