Local Features of the Fermi Surface Curvature and the Anomalous Skin Effect in Metals

Abstract

In this paper we present a theoretical analysis of the effect of local geometrical structure of the Fermi surface on the surface impedance of a metal at the anomalous skin effect. We show that when the Fermi surface includes nearly cylindrical and/or flattened segments it may significantly change both magnitude and frequency dependence of the surface impedance. Being observed in experiments these unusual frequency dependencies could bring additional information concerning fine geometrical features of the Fermi surfaces of metals.
