Abstract

The current density distribution and the surface impedance of high-Tc superconducting microstrip lines and their temperature dependence are investigated using the full-wave Finite Difference Time Domain FDTD) technique. Appropriate modifications to Maxwell's equations are incorporated to take into consideration the two-fluid London model that describes superconductivity. The supercurrent density and the average supercurrent density are calculated as function of temperature and the width of the microstrip line. In addition, the surface resistance and reactance as function of temperature and frequency have been calculated and compared to published results.
