This article provides one EMC engineer’s perspective on the important aspects of the history of Part 15 - Low Power Devices, under the Federal Communications Commission’s rules.

Naval ships have lots of powerful radars and radios that create electromagnetic interference. Scientists studied how this interference leaks into protected rooms through wire holes, discovering new mathematical patterns that help predict when sensitive equipment might be damaged by electromagnetic waves.

As connected medical devices become more integral to patient care, ensuring their cybersecurity is critical to both patient safety and regulatory compliance. This article explores how the IEEE 2621™ standard and its associated certification program provide a structured, standards-based approach for engineers to design, validate, and secure these devices throughout their lifecycle

Discover the exact mathematical solution for far-field shielding effectiveness of solid conducting shields. Learn how reflection, absorption, and multiple-reflection losses combine to determine a shield's ability to block electromagnetic radiation in real-world applications.

USB-C's high-speed data lines need robust ESD protection, but TVS device placement matters critically. New research reveals why positioning protection behind AC coupling capacitors—not in front—delivers superior IC protection for sensitive SuperSpeed applications.

Full-wave EMC simulation tools are powerful — but often too slow, too costly, and too complex for real-world troubleshooting. Dr. Min Zhang makes the case for free SPICE-based tools, walking through three field scenarios where quick models helped isolate failures, validate test setups, and guide next-generation designs.
