This part of IEC 61788 describes measurement of the surface resistance of superconductors at microwave frequencies by the standard two-resonator method. The object of measurement is the temperature dependence of Rs at the resonant frequency.

The applicable measurement range of surface resistances for this method is as follows:

–   Frequency:                      8 GHz < f < 30 GHz

–   Measurement resolution:   0,01 mW at 10 GHz

The surface resistance data at the measured frequency, and that scaled to 10 GHz, assuming the f 2 rule for comparison, shall be reported.
