Skin Effect and Shielding Theory of Schelkunoff

Abstract

A basic knowledge and understanding of the theory of the skin effect and eddy currents are necessary so that efficient measures are taken to achieve the EMC of an arrangement. The current in a conductor flows more and more on the surface of a conductor with increasing frequency due to the so-called skin effect. More accurately, it flows in a thinner and thinner layer on the surface of the conductor. The skin effect is often referred to as the effect of current displacement (to the exterior). In annex chapter A6.1, the theory is applied to the conducting half space and it is shown that cylindrical conductors can also be treated in a very simple way.
