High electric conduction property of composite copper-clad steel wire

摘要

The authors of this paper discover the high electric conduction property of the composite copper-clad steel wire; that is to say, in a specific frequency domain, its electric conduction property is higher than that of copper wire having the same diameter. This paper describes the relationship between this high conduction property as a function of the frequency and structure of the wire and points out that the property results from the reflection of an electromagnetic (EM) wave at the interface inside the composite wire.
