The Mattis and Bardeen theory describing the anomalous skin effect in superconductors is exactly solved for thin films and bulk material. When five material parameters, i.e., the energy gap, the critical temperature, the London penetration depth, the Fermi velocity and the mean free path are known, calculations of all frequencies, mean free paths and temperatures can be carried out and summarized to form the surface impedance. In this paper it is shown that the solution in the extreme anomalous limit cannot describe these measurements and that the Mattis and Bardeen theory is well able to describe measurements on strong-coupling superconductors.
