Abstract :
A miniaturized YBa/sub 2/Cu/sub 3/O/sub 7-x/ coplanar stripline structure is investigated theoretically. The field calculation, on which the results are based, was performed by means of a partial wave synthesis which took into consideration the exact field distribution within the superconducting regions. The high-T/sub c/ superconductor material is described by the two-fluid model and the London theory. Approximation formulas for effective permittivity, attenuation, and characteristic impedance are deduced from the numerical results.<>
