T1 GRAZING INCIDENCE REFLECTIVITY OF HIGH-Tc SUPERCONDUCTORS: MM WAVE TECHNIQUE OF CONDUCTIVITY MEASUREMENTS JF Telecommunications and Radio Engineering JO TRE YR 2011 FD 2011-09-28 VO 70 IS 14 SP 1277 OP 1285 K1 grazing incidence reflectivity K1 microwave conductivity K1 superconducting films AB Non-resonant nondestructive technique has been described for investigation of high-temperature superconductive and relative materials through the measurement of the microwave reflection at grazing incidence. As authors discussed earlier, a reflection coefficient of the electromagnetic wave at grazing incidence can be used to determine an absolute complex conductivity over a wide temperature and frequency range. As of now the experimental measurement setup was realized in millimeter wave range using waveguide phase bridge based approach. The conductivity of ΥBa2Cu3O7−δ film was measured at temperatures higher than critical.
