| 摘 要： | 在非均匀耦合传输线瞬态响应灵敏度分析中,提出了一种基于精细积分法的分析方法.这是一种半解析的时域分析方法,该方法将非均匀耦合传输线时域电报方程在空间差分离散,建立起传输线瞬态响应及传输线瞬态响应灵敏度对时间的一阶微分方程,通过分步积分,从而将求解传输线瞬态响应灵敏度问题转换成了求解传输线瞬态响应问题,极大地简化了问题的分析.该方法具有算法稳定、简单、精确及通用性强等特点,能够分析任意类型的传输线及负载.算例结果表明了文中方法的正确性和有效性.

| Abstract: | A semi-analytic method in time domain with precise integration is proposed for sensitivity analysis of transient response of nonuniform coupled transmission lines,the lines axis x is discretized in Δx increment,the telegraph equation of nonuniform coupled transmission lines in time domain is differenced,and transformed into a set of first-order differential equations of transient response of transmission lines and the sensitivity with respect to time,then the sensitivity analysis of transient response of coupled transmission lines is transformed into the calculation of its transient response by decomposition integration to significantly simplify the sensitivity analysis of the transient response of nonuniform coupled transmission lines.This method enables to simply and stably analyze random types of transmission lines and loads,and the examples show its correctness and effectiveness. |
