| 摘 要： | 该文利用电磁场时域有限差分研究了恒定电压下光导开关Blumlein线电脉冲的传输特性.首先用达朗伯公式行波法分析了Blunlein线的工作原理,针对具体工作情况的要求,分别提出了电磁场时域有限差分下处理边界条件的方法和源的预置方法,针对光导开关提出了表面阻抗模型.计算给出了处于恒定电压下的光导开关Blumlein电脉冲产生和传输的过程,给出了电脉冲的时间分布.实验结果证明了所进行的电磁场时域有限差分分析结果是正确的.最后进一步分析了Blumlein线输出电压与结构的关系.

| Abstract: | The characteristics of electromagnetic pulse produced by Photo-Conductive switches and Blumlein line under the bias voltage is studied by FDTD. The D’Alemberts formula is used to analyze the principle of Blumlein line. A total reflection border and the source method are given for the situation that Blumlein line worked under bias voltage. The SIBC is used to model the PCSs. The propagation of pulse is computed. The waveform of different time is given. The experiment result agrees with the numerical result well. The relation between geometry and output voltage of Blumlein line is studied. |
