| Abstract(in English) | Using the microstripline resonator method, we can measure all of the values of the surface resistance. Rs and magnetic penetration depth, λ of superconducting thin film and the dielectric constant, ε_r and dielectric loss, tan δ of dielectric substrate, which are important parameters for designing superconducting microwave passive devices. However, the microstripline resonator method for accurate measurement of the values of the Rs and the λ has not yet been examined systematically. We investigated the effect of the thin film thickness on accuracy of the values of the Rs and the λ. The results show that in order to increase the accuracy of the Rs and the λ, we must take into consideration the thickness of the stripline. The Rs λ of YBCO thin film were measured using the microstripline resonator method. The Rs was 177.2μΩ at 3.9 GHz and at 21K, and the λ(0) was found out to be 0.37μm. |
