Abstract
The parallel plate dielectric resonator was applied to surface resistance (Rs) measurement of high temperature superconducting films with small area for the purpose of material research in early stage. Using 38 GHz resonance of TE013 mode, available measurement area in the film was diameter of 9 mm. From the theoretical calculation, the measurement at higher frequency had an advantage of less error in Rs that is caused by dielectric loss tangent (tan δ). The effect of dielectric loss is negligible at 38 GHz even using a sapphire with order of 10-7 of tan δ. In lower Rs region, Rs values of YBa 2Cu3Oy that were measured at 38 GHz agreed well with that of standard measurement method at 22 GHz. However the difference of Rs between two methods became larger with increase of R s. It is owing to poor signal to noise ratio at higher frequency.
