摘要: 本文將一種時(shí)間序列預(yù)測方法與二維時(shí)域有限差分(FDTD)法相結(jié)合，并應(yīng)用于均勻微波平面?zhèn)鬏斁€的特性參數(shù)計(jì)算。該混合方法特別適用于尺寸很細(xì)微的MMIC傳輸線，而且可以精確地計(jì)算非理想導(dǎo)體的損耗。與傳統(tǒng)的FDTD法相比，大大節(jié)約了計(jì)算時(shí)間，提高了效率。計(jì)算結(jié)果與測量非常一致。

Abstract: 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. -
