  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.
