Attenuation, phase velocity and current density distribution in high critical temperature superconducting planar transmission lines

Electromagnetic calculation of propagation parameters for high Tc superconductive coplanar and microstrip transmission lines is presented. Calculations are performed by a nodal circuit simulator (SPICE), with possibility of direct interfacing with CAE standards. The results are in good agreement with data obtained with a full-wave analysis and CPU time is much smaller than in standard MW applications. Then, current density distributions are shown.
