| Abstract: | 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 165 MHz was obtained in the experiment, preliminarily verifying the feasibility of producing wideband pulse with NLTL. |
