Classical Shielding Theory vs. Near-Field Measurements
This article addresses the fundamental concepts underlying the classical shielding theory based on Schelkunoff’s equations [1]. In order to assess the applicability of these equations, an understanding of their origin, assumptions made in their derivations, and their limitations, are needed. […]
What You See With Near Field Probes
In EMI/EMC troubleshooting, near field probes (NFPs) are great tools. Let’s review how to understand what you really see at the screen of your instrument with a magnetic near field probe. EMI/EMC problems (radiated and conducted emissions) are usually related with current […]
What is the Number One Item That Causes EMC Problems at the Board Level?
There are many “rules” for laying out a printed wiring board (PWB) to minimize generation of EMI from a board. These cover a wide range of issues that are important. Some more than others, but all can be important. But, […]
