摘要 介绍了非线性传输线的工作原理和色散特性,给出了用于模拟交叉耦合磁饱和非线性传输线的计算方法。算法基于传输线各节点的时域差分方程组进行步进迭代,其中利用J-A模型描述传输线中NiZn铁氧体磁芯的非线性磁化行为,并模拟了非线性传输线的工作方式。实验获得了中心频率165MHz的宽带脉冲输出,初步验证了用于产生宽带电磁脉冲的非线性传输线关键技术。 The working principle and dispersion characteristics of nonlinear transmission line(NLTL)are discussed,and a simulation method is proposed for analyzing across coupled and magnetic saturation NLTL.This method is based on time-step iteration of finite difference equations of each circuit nodes,and the J-A model is employed to describe the magnetizing behavior of NiZn ferrite beads in this method.We simulated an NLTL operation mode,and a center frequency of wideband pulse of 165MHz was obtained in the experiment,preliminarily verifying the feasibility of producing wideband pulse with NLTL.
