摘要

利用时域有限差分法(FDTD)研究了高斯脉冲在超导共面波导上的瞬态传播。采用双流体模型来描述超导性。通过存储电场历史,用时域有限差分法对电导率随频率变化的负虚部进行建模。采用二阶精度的可变网格对超导体薄膜和缓冲层进行了解析。

Signal Propagation in Conductor-Backed Superconductor Coplanar Waveguides
Transient propagation of Gaussian pulses on superconductive conductor-backed coplanar waveguides are investigated using the Finite Difference Time Domaim Method (FDTD). The two-fluid model is used to describe the superconductivity. The frequency-dependent negative imaginary part of the conductivity is modeled with the FDTD by storing the electric field history. A variable mesh with second order accuracy is used to resolve the thin superconductor film and buffer layer.
