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. This tutorial article addresses each of these points. The goal is not to show the … [Read more...]
