| 摘 要： | 针对螺旋线型三导体脉冲形成线的快波振荡问题,提出一种阻抗分两段阶梯变化的螺旋线结构,分析了此类螺旋线快波反射与慢波反射相互抵消快波的条件,给出两段变阻抗螺旋线慢波系数之间的关系式以及匝数密度之比计算方法,通过仿真计算证明该方法能有效消除快波反射对螺旋线输出脉冲的影响。

| Abstract: | A novel spiral pulse forming line with oscillating and variable impedance is presented, which can neutralize fast-wave oscillation in previous spiral line with inner conductor and outer shield. Offsetting conduction of two fast waves respectively induced by reflected fast wave and reflected slow wave in such a spiral line is analyzed. Some relationship formulas, such as slow-wave coefficients and turns densities, of two variable impedance spiral sections are given. Simulative results show that such method can effectively neutralize the fast wave influence on the output pulse of the previous spiral line. |
