When your circuit misbehaves with unexplained noise and jitter, you're facing electromagnetic coupling. This practical guide walks engineers through identifying whether problems stem from differential or common mode issues, near-field or far-field effects, and provides a systematic debugging workflow to isolate sources, paths, and receivers—getting your design back on track.

Understanding how shields perform in the near field requires accounting for wave impedance differences between electric and magnetic sources. This sixth installment derives shielding effectiveness formulas for near-field conditions and reveals a surprising truth: copper outperforms steel at low frequencies, but steel's superior absorption reverses this advantage above 4kHz.

Discover how strategically placed stitching vias serve as the unsung heroes of PCB design, maintaining ground plane integrity while minimizing electromagnetic interference. Learn essential techniques for achieving regulatory compliance and optimal signal performance in today's demanding electronic applications.

Don MacArthur explores essential EMC test chambers—from anechoic to reverberation types—used across industries like automotive, aerospace, and consumer electronics. Learn key design considerations including material selection, shielding effectiveness, and applications ensuring electromagnetic compatibility compliance.

Electronics compliance encompasses EMC, safety, and environmental standards essential for device success. This article covers critical design considerations including component selection, PCB layout and placement, and thermal management strategies for achieving regulatory compliance.

Commercial EMI testing requires strict pass/fail criteria with no allowances for upset. Military/aerospace susceptibility testing uses higher levels but allows more flexibility - equipment may be acceptable despite susceptibility at specific frequencies if those frequencies won't be encountered operationally, prioritizing practical deployment considerations.

This article introduces an upcoming Technical Report (TR18) from the ESD Association on Electronic Design Automation checks. It details integrated ESD verification throughout IC design phases, covering schematic-based topological checks and layout-based verification to ensure comprehensive ESD protection in modern circuits.
