Effects of Meissner surface current on the microwave surface resistance of type-II superconductors

Influence of the Meissner current on the field-induced variations of the microwave (mw) surface resistance in type-II superconductors is demonstrated to be well reproduced by exploiting different critical state models. Rs(B)/Rn versus Ba curves have been obtained using Kim and exponential type Jc(B) considering Meissner current circulating at the surface of the superconducting specimen.
