Abstract(in English) | For microwave measurement of surface resistance R_s of superconductors, measurement precisions are discussed for dielectric resonator methods of two types ; one uses a TE_011 resonator and a TE_013 resonator (a two-resonator method) and the other uses TE_012 and TE_021 modes of a dielectric resonator (a one-resonator method). It is found that measurement error for R_s of YBCO films is 10 percents for the two-resonator method using sapphire rods and 40 percents for the one-resonator method using BMT ceramic rod. Therefore, it is essential to use the low loss dielectric material for the measurement low R_s value. Moreover, we calculate the best diameter to length ratio of dielectric rod to measure the superconductor plates and films with the smallest area. |
