摘要: 本文提出了計算偏心特種截面?zhèn)鬏斁€特性阻抗的部分模擬電荷法。由于外導體邊界1上的邊界條件準確滿足,所以這種方法精度較高、且計算量小。文中提出用高斯列主元消去法與最優(yōu)化方法相結合的技術求解模擬電荷方程組,是提高精度和保證收斂的一種有效算法。文中給出了外導體邊界1為圓形、橢圓形、矩形、槽形和平板形五類傳輸線的Green函數(shù),且對特性阻抗值進行了計算。Abstract: The partial charge-simulation method is presented to solve the characteristic impedance of transmission line of specific cross-section with offset inner conductors. This method has a higher accuracy due to the accurate satisfaction of the boundary condition on the outer conductor. The combined method of gnass elimination and optimization is used to solve the equation of charge-simulation, and it is an effective method for increasing the accuracy and assuring the convergence. The Green's functions of five transmission lines (i.e.with circular, elliptic, rectangular, trough and slab outer conductor) are given.
