摘要

摘要: 铁氧体传输线的脉冲陡化技术能够实现高频高功率快前沿脉冲输出，且具有固态化和紧凑化优点，已广泛应用于高功率微波源。关于铁氧体传输线脉冲陡化特性的仿真计算缺乏较为精确的模型，因此利用COMSOL仿真软件建立了铁氧体传输线仿真模型，考虑电磁波传播与磁芯磁化进动之间的相互影响，将Maxwell方程与Landau-Lifshitz-Gilbert （LLG）方程结合进行仿真计算，与实验结果进行对比验证了仿真模型的准确性。再在此模型基础上，研究了不同传输线长度、不同电压幅值，以及不同外加偏置磁场对脉冲波形的影响。结果表明：脉冲前沿随传输线长度的增大及电压幅值的增大而减小；外加偏置磁场对脉冲前沿有影响，选择合适的外加偏置磁场可以实现最小脉冲前沿输出。

Abstract: The pulse steepening technology of ferrite transmission lines can realize high-frequency and high-power fast front pulse output and has the advantages of solid-state and compactness. It has been widely used in high-power microwave sources. The simulation calculation of pulse steepening characteristics of ferrite transmission lines lacks a more accurate model. Therefore, this paper establishes the simulation model of the ferrite transmission line by using COMSOL simulation software, considering the interaction between electromagnetic wave propagation and magnetic core magnetization precession. The Maxwell equation and Landau-Lifshitz-Gilbert (LLG) equation are combined for simulative calculation. Compared with the experimental results, the accuracy of the simulation model is verified. Based on this model, simultaneous interpreting of the effect of different transmission line lengths, voltage amplitude, and external bias magnetic field on pulse waveform is studied. The results show that the pulse front decreases with the increase of transmission line length and the increase of voltage amplitude; The output of the minimum pulse front can be realized by selecting an appropriate external bias magnetic field.
