摘要：
In this paper, a compact two-dimensional (2-D) finite-difference time-domain with weighted Laguerre polynomials (WLP-FDTD) for superconducting microstrip line is proposed. Superconductors are modeled by the two-fluid model and London equations. The formulations of the compact 2-D WLP-FDTD for superconducting microstrip lines is derived. Compared with the conventional 2-D FDTD method, the compact 2-D WLP-FDTD method is not restricted by stability condition. Therefore, it avoids high computational complexity due to fine grids inside the superconductor and small time step limited by the stability condition. A typical superconducting microstrip line is simulated and the results of the proposed WLP-FDTD method are compared with those of the 2-D FDTD method. It is shown that the proposed WLP-FDTD method for superconducting microstrip lines has good accuracy and high efficiency.
