Abstract
Errors in measurements of surface resistanceR s of HTS materials are due to discrepancy between a mathematical model describing physical phenomena and a real measurement environment, finite accuracy of measurements of theQ-factor, and finite accuracy of constants used for calculation ofR s . In this paper we analyze errors inR s due to uncertainties in theQ-factor, geometrical coefficients, loss tangent,R scu, and other factors when a cylindrical copper cavity with an HTS end plate, a stripline resonator, and sapphire rod resonators are used for HTS characterization.
