Raven M. Electromagnetics and Experimental Measurements of the Skin Effect 2026

Textbook in PDF format

The skin effect is the tendency of alternating current (AC) to flow primarily near the surface of a conductor, rather than being evenly distributed, and this effect becomes more pronounced as the frequency of the AC increases. This is important because it increases the effective resistance of the conductor, leading to higher power losses and potential overheating. It can impact the design and performance of circuits, transmission lines (or waveguides), and antennas and is thus an important effect to be able to measure and control
