Abstract :
Broadband measurements have been done on high Tc superconducting coplanar lines of YBa2Cu3O 7 on [100]MgO substrates. From the transmission and reflection coefficients of coplanar lines, the characteristic impedance, attenuation constant, phase constant, group velocity, and London penetration depth of the film are derived, based on the circuit models
