Some of the Many Stories of Medical EMI
Introduction I have been collecting stories about EMI for a long time, publishing many of them in the ‘Banana Skins’ column of The EMC Journal, www.theemcjournal.com. Some come from official reports, some from anonymous whistleblowers, some are amusing, and some concern deaths and injuries. At the present time, I have published 855 of them, all indexed by application and by … [Read more...]
EMI Basics and Board Level Shielding Design
Introduction In today’s world full of digital electronic devices, electromagnetic interference (EMI) is a major concern in both military and commercial marketplaces. Electrical equipment can become susceptible to these undesirable emissions and malfunction due to their presence. The simplest and most cost-effective method for reducing EMI is to first attack it at the board … [Read more...]

Can 5G Sites Be Good Neighbors?
Baseball Hall of Famer Yogi Berra was notable for his skill on the field and was equally notable for many of his quotes. “Yogi-isms” were things he often said that were both amusing and insightful. Referring to a popular restaurant, he said, “Nobody goes there anymore; it’s too crowded.” Sounds like a contradiction, but it’s easy to follow his meaning. Customers chose not to … [Read more...]
Drag Races, a Cashless Society, and the Threat of EMP
About a month ago, my 12-year-old son and I made his first-ever trip to the NHRA Drag Races near our home. It’s something that I always did with my dad, and I have looked forward to taking him ever since he was born. It’s a typical father-and-son day, wrought with loud, fast cars, terrible food, and the occasional waft of nitromethane fuel in the air. The drive is about … [Read more...]
