摘要
在耦合传输线的瞬态分析中提出了一种基于精细积分法的龙格 库塔迭代法。这是一种时域内的数值解法,该方法在对电报方程进行空间离散而获得对时间的一阶微分方程之后,没有采用精细计算法,而是采用了龙格 库塔迭代法。避免了大量的矩阵运算,提高了传输线瞬态响应分析的效率。
A new time domain method, Runge-kutta iteration based on precise integration, is presented to analyze the transient response of coupled transmission lines. It is a numerical method. By discreting the telegraph equations in space, a first order differential equation respect to time is obtained, then Runge-Kutta iteration instead of precise integration is applied to solve the equation. This method can avoid large amount of matrix calculation and improve the analysis efficiency of coupled transmission lines.
