THE APPLICATION OF A TIME SERIES PREDICTION METHOD TO TWO-DIMENSIONAL FDTD METHOD

本文将一种时间序列预测方法与二维时域有限差分(FDTD)法相结合,并应用于均匀微波平面传输线的特性参数计算。该混合方法特别适用于尺寸很细微的MMIC传输线,而且可以精确地计算非理想导体的损耗。与传统的FDTD法相比,大大节约了计算时间,提高了效率。计算结果与测量非常一致。

An efficient time signals prediction method combined with two-dimensional finite difference time domain (2D-FDTD) method has been proposed for the performance parameters computation of uniform microwave transmission lines. This hybrid method is especially suitable for the micron structures, and can account for the conductor loss efficiently. So it leads to a significant reduction in CPU time as compared with the conventional three-dimensional FDTD, which improves the efficiency. The simulation results are in good agreement with the results obtained by measurements.
