How can the EMI/EMC community continue to blame this accident on electromagnetic interference (EMI) from the USS Forrestal’s on-board AN-SPS-43 search radar when the official US Navy inquiry comes to different conclusions?

Change is the only constant. A product lifecycle approach underpinned by a proactive and reactive regulatory and compliance strategy is key to success. Using digital tools to augment that process generates faster yet reliable data and results to bring safer medical devices to market that improve patient outcomes.

This series of articles delves into the design principles of power filters for switched-mode power converters and similar applications, focusing on conducted and radiated emissions. Part 2 will examine specific aspects of switched power converters.

This first installment in a two-part series evaluates inductor impedance using S11 parameters across one-port shunt, two-port shunt, and two-port series methodologies. Experimental results reveal significant discrepancies between measured values and manufacturer specifications, highlighting limitations in S11-based impedance characterization techniques.

The teaser maintains a technical, authoritative tone that should appeal to engineering professionals while highlighting the article's key experimental findings. It addresses the misconceptions about AC ionizer safety and emphasizes the quantitative approach taken in the study, which should generate interest among readers concerned with ESD protection in semiconductor manufacturing environments.
