Abstract :
The method allows investigation of the superconductors conductivity of which changes under different external conditions such as temperature, magnetic field, etc. The possibility to obtain such HTS characteristics as complex conductivity or surface impedance using measured complex reflection coefficient, calibrated by absolute values of reflection coefficient of the known materials, has been shown. The applicability of the method to investigating peculiarities of microwave properties of unconventional superconductors in normal state was shown as well.
