Abstract

The behavior of an inhomogeneous superconductor in an external ac field is studied. General equations describing the ac response are formulated. Special attention is paid to the case of a layered conductor containing superconducting “islands.” A system of this type displays “pseudogap” properties. The surface impedance Z is evaluated. It is shown that ReZ≠|ImZ| and that their difference is ΔZ∝ω−1/2, where ω is the frequency of the ac field.
