High-frequency conductivity, classical and anomalous skin effect of eutectic silver-copper composite wires

It is shown that the theoretical form of the anisotropy of the high-frequency surface resistance of a metal having spheroidal energy surfaces, calculated exactly by Sondheimer, may be obtained also in the extreme anomalous limit by means of the ineffectiveness concept. This result is taken to justify the application of the simpler ineffectiveness method to metals having Fermi surfaces of any form, and it is shown that the resistance is related solely to the geometrical shape of the Fermi surface. The possible application of this result in the study of metals is discussed.

Overvoltage Protection

The paper discusses the prospects of using nanocrystalline amorphous materials in the electric power industry. In particular, in the field of protection of electric power equipment of substations from high-frequency pulses. The effectiveness of using such materials to activate the anomalous skin effect in multilayer conductors is shown. The resulting conductors increase their resistance at lightning frequencies, thereby making it possible to create devices that effectively suppress high-frequency pulses. The authors give an example of a protective frequency-dependent device using nanocrystalline ferromagnetic material and the results of its use in trial operation. The paper shows the results of comparing round and flat frequency-dependent conductors.
