Microwave properties and modeling of high-T/sub c/ superconducting thin film meander line

Meander lines have been utilized for characterizing laser-deposited, thin-film, high-T/sub c/ superconducting material. The dispersion characteristics of the meander line have been modeled and the power dependence of high-T/sub c/ materials as a function of frequency and temperature has been investigated. Measurements showed that magnetic fields as low as 0.1 Oe will affect the superconducting material, decreasing the Q of the meander lines. The Q deterioration is temperature and frequency dependent and the latter is less pronounced at higher frequencies.<<ETX>>
