Abstract :
The propagation properties of a superconductive stripline are analyzed by a rigorous method. The superconductor is treated as a general dielectric material with the real part of the dielectric constant being negative. The frequency-dependent propagation constant and loss factor of the line are obtained by solving nonlinear dispersion relations. Compared with normal metal lines, superconductor lines offer low loss and low dispersion and are suitable for high-speed integrated-circuit interconnections. The simulation results for both low-T/sub c/ and high-T/sub c/-transmission lines were compared with those obtained by a perturbation approach to assess the validity of the perturbation method. Some other issues, such as penetration depth, are also discussed. The analysis method is applicable to general superconductor boundary value problems.<>
