When the FCC issued FCC 16-74 and extended the 2.948 Listing program, the pressure driving US-China MRA negotiations evaporated with it. Unpack what the ruling actually says, what the KDB fine print reveals, and whether any real leverage remains for moving MRA talks forward.

As connected devices multiply and wireless networks grow denser, EMC engineers face a landscape that keeps expanding in scope and complexity. This piece examines how IoT, 5G, and Machine-to-Machine communications are reshaping the practice of EMC — and what compliance professionals need to understand to keep pace.

A 1988 study of current distribution in printed circuit boards reveals how return‑current paths, ground‑plane impedance, and trace coupling drive EMI and signal‑integrity issues. Its insights on low‑impedance ground structures remain foundational for today’s high‑speed digital designs.

This article is an update of a previous piece that was published in the...

Much has been written on the subject of radiated emissions and it is with pleasure that I have been given the opportunity to review the Third Edition of Controlling Radiated Emissions by Design by Michel Mardiguian (with contributions by Donald. L. Sweeney and Roger Swanberg).

From dark‑matter satellites to radiometric sensing, this piece explores how modern space science uses electromagnetic energy to probe the deepest structures of the universe. Along the way, it links real‑world cosmology with pop‑culture space adventures—and the challenges of funding true scientific discovery.

Back in my novice days, computers puttered along at 4.77 MHz and we rarely...

The measurement of Specific Absorption Rate (SAR) is arguably the most complex of compliance issues, affecting thousands of new device models and billions of radio transmitters.

Three million years ago, Homo Naledi may have gazed at stars seeking answers. Decades ago, the COBE satellite measured echoes of the Big Bang. One question endures across time: how did this all start? A journey from ancient cosmology to space-age EMC.

The wireless revolution hiding in your pocket: Between 2004 and 2014, FCC certifications exploded fivefold globally, but the real shocker? China's certifications skyrocketed 25-fold to dominate the market, while Mexico went from one lonely grant to 286. Discover which countries are secretly powering your connected life—and why your backpack now carries more radios than a 1990s electronics store.
