Abstract

The purpose of this talk is first to summarize a paper to be published in Radio Science in the near future. When both the resistivity and the thickness of a conducting film tend to zero, the properties of the infinitely thin resulting film depend on how the two vanishing parameters are linked during the limiting process. It is worth noting that a model, in which a surface current gives rise to the Joule effect, is perfectly conceivable, In the same way, when both the resistivity and the thickness of a rod tend simultaneously to zero, the properties of the infinitely conducting and infinitely thin strip that we get at the limit are difficult to describe. For example, they may depend on the shape of the cross section of the initial rod... We also present the results of a very simple numerical study that anyone can verify with his own microcomputer. Maybe practical people will prefer this study to theoretical considerations.
