Skin Effect and Surface Currents

Skin Effect and Surface Currents
A visualisation technique that helps us to do good EM Engineering
By Keith Armstrong, Cherry Clough Consultants Ltd
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.
This is because visualizing skin effect and surface currents is much easier than trying to visualize what is really going on – the propagation of electromagnetic (EM) waves and fields – and so it more easily provides valuable insights into good EM engineering.EM engineering includes the disciplines of signal integrity (SI), power integrity (PI) and electromagnetic compatibility (EMC).
