Abstract: The technique proposed by authors earlier for accurate measurement of large-area HTS thin film surface resistance (R-s) is developed further. It is based on application of quasioptical dielectric resonators (QDR). Data on R-s of individual Y-123 films obtained at 77 K by using "round robin" procedure are presented. The main attention is paid to developing technique of temperature dependence measurement of thin film surface reactance variation (Delta X-s). The dependence obtained by experiment is analyzed by means of fitting procedure that allows one to determine the validity of theoretical models for the temperature dependence of field penetration depth. Particularly, the 3D XY critical regime, Ginzburg-Landau behavior and two-fluid model are compared near T-c. Our data show that the former approach best follows the observed dependence.
