Notes:
The surface impedance of bulk and thick film granular high temperature superconductors has been studied. The static magnetic field, temperature, and frequency dependence of the surface impedance have been analyzed in terms of the weakly coupled grain model. Accurate quantitative predictions of the frequency dependence of the surface resistance are made using this model. The model also quantitatively accounts for the negative magnetic field coefficient of the effective rf penetration depth. The rf penetration depth is a maximum when the ratio of penetration depth to skin depth is 0.930.
