Abstract
A correct phenomenological model of the microwave surface impedance of a high-temperature superconducting (HTS) film with reduced number of fitting parameters is presented. Simple empirical expressions are prop osed for London penetration depth at T = 0 K and for the residual resi stance parameter alpha versus the fitting parameter gamma considered a s a figure of merit of the HTS film at microwaves. The model is verifi ed by a comparison of results of modeling and measurement data in a wi de temperature range. (C) 1997 John Wiley & Sons, Inc.
