A helpful article from In-Compliance magazine describing the practical implications of skin effect on product design, particularly sheilding.

Understanding skin effect and surface currents saves us a lot of time and cost in the design of our product’s shielding and filtering, especially for tough EMC standards such as automotive, military or aerospace. It also helps us to more quickly achieve many other issues in cost-effective EMC design.

In this article, instructor Arturo Mediano shares a tip on how you can use the vector network analyzer to gauge the shielding effectiveness of different materials.

Article by instructor Arturo Mediano about near-field scanners.

I love near field probes because they let me "see" magnetic and electric fields with an oscilloscope or with a spectrum analyzer. They let locate sources of emissions in board, cables, and systems. Near-field scanners also let you see emissions, particularly all over a board. That's hard to do with a single probe.

This blog post is a few years old, but remains very interesting to see the difference in performance among USB wall chargers. Ever wonder about the difference between the expensive name-brand charger and the cheap imitation? This article gives in depth examination of the noise emanating from these devices. An interesting side effect of unwanted electrical noise from the chargers is that the touch-screen on your device can become unresponsive or erratic in some cases.
