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. R(s)(B)/R(n) versus B(a) curves have been obtained using Kim and exponential type J(c)(B) considering Meissner current circulating at the surface of the superconducting specimen.
