FIELD SOLUTION FOR A THIN-FILM SUPERCONDUCTING PARALLEL-PLATE TRANSMISSION-LINE

By using Bose statistics and the Gorter and Casimir model for a two-fl uid model, London's equations, and the classical skin effect for the n ormal component of the current, a sinusoidal wave solution is found fo r a superconducting transmission line. This solution gives expressions for the phase velocity and attenuation coefficient which are used to compare the behaviour of a wave in LTS's and HTS's and to investigate the value of the Q-factor of a parallel-plate resonator. The computed values of the Q-factor are compared with measured data in the literatu re.
