It doesn’t take a crystal ball to know where the future of wireless is heading. With inexhaustible demand driven by 5G, 6G, and beyond, ultra-high-definition video, autonomous cars, security applications, and IoT, the sky's the limit for utilizing the higher ends of the electromagnetic (EM) spectrum. Meeting this demand requires products capable of capitalizing on the … [Read more...]
The Emerging Threat of Tactical Electromagnetic Interference & Its Spread into Non-Defense Sectors
During the last five years intentional electromagnetic interference (IEMI) has emerged as a credible and increasingly likely threat to commercial and defence facilities alike, with a potentially crippling cost to individual organizations of such a localized attack. Hollywood has long used electromagnetic interference (EMI) and electromagnetic pulse (EMP) phenomena as the de … [Read more...]
The Top Five Reasons Products Fail EMI Testing
Introduction The three top product failures I see constantly in my consulting practice are (1) radiated emissions, (2) radiated susceptibility, and (3) electrostatic discharge. After reviewing and testing hundreds of products over the years, I’ve come to the conclusion that products fail these tests for five common reasons (somewhat in order of incidence); PC Board … [Read more...]
EMI Pre-Compliance Testing
Introduction This article describes how I perform pre-compliance testing for the top four EMI issues I constantly run into; conducted emissions, radiated emissions, radiated immunity, and electrostatic discharge. Of these, the last three are the most prevalent issues, with radiated emissions typically being the biggest compliance challenge during certification testing. If … [Read more...]

Controlling EMI in High-Speed PCB Design
Patrick Carrier - Mentor Graphics, a Siemens Business Antennas come in all shapes in sizes. In addition to wireless communications, they are becoming ubiquitous in the automotive space as well. Similarly, very high speed digital circuits are pervading these realms. It is the unintentional creation of antennas in these high speed digital circuits that cause Electromagnetic … [Read more...]
Cable Discharge Event (CDE)
Abstract Worst-case Cable Discharge Events (CDE) are poorly understood by most of the product developers as the definition of what is about to happen when you plug in a cable into an appliance’s socket. It is NOT the electro-static charge which could be expected on the cable: outer/inner shield(s) + internal wires, while the cable is fully floating prior to the cable … [Read more...]
Do Not Miss the EMC + SIPI 2019 Symposium!
