High-frequency impedance of a pure type I superconductor in the surface superconductivity regime
Varlamov A.A.
The surface impedance of a pure type I superconductor is calculated for surface superconductivity conditions. In view of low impurity concentration, the anomalous skin-effect regime is realized for the incident electromagnetic wave. It is shown that the superconducting currents, which flow along the superconductor surface perpendicularly to the constant magnetic field, provide the main contribution to the reflection of the electromagnetic wave. A comparison with experiment is made, yielding good agreement.
