How Do Magnetic Fields Penetrate Shielding Materials?

Characterization of Shielding Materials

This article is the first part of a trilogy that aims to introduce a new paradigm in the measurement of specific electromagnetic shielding materials, namely shielding materials made from woven conductive threads. These articles highlight the shortcomings of common methods in the evaluation of such materials and introduce new approach and methodology to measure them. This new paradigm emphasizes characterization of shielding materials based on magnetic field rather than electric field. The new method introduces a measurement setup and lumped element model intrinsic to the material and independent from the measurement method.

A Three-Step Process for Characterizing Self-Generated Interference for Wireless or IoT Products

The proliferation of electronic products has made compatibility between devices increasingly important. Products must not interfere with one another and must be designed to be immune to external energy sources. Kenneth Wyatt helps product designers or EMC engineers learn how to characterize this self-generated EMI so that these issues are addressed early when costs and design changes are minimized.
