What is Skin effect?

The concentration of high-frequency current near the surface of a conductor, which raises its effective resistance. The higher the frequency, the thinner the surface layer carrying the current.

Field: Interconnect processes

Skin effect in the explanations

In traces, conductor loss from the skin effect and dielectric loss from the board material both grow with frequency.
