摘要

A numerical analysis of the microwave propagation characteristics of a high-temperature superconducting microstrip transmission line is presented. It is based on the transmission line theory and empirical two-fluid model which appropriately incorporates the quasiparticle scattering and residual loss of the superconductor. First, the calculated attenuation constant and phase velocity are compared with those predicted by the conventional two-fluid model for a YBa 2Cu 3O 7-δ microstrip line with a linear substrate, lanthanum aluminate, LaAlO 3. Next, we have specifically investigated the effects of nonlinear substrate such as strontium titanate, SrTiO 3, on the attenuation constant and phase velocity. The tunable feature of such a microwave device owing to the nonlinear dielectric ferroelectric is illustrated and discussed.
