| 摘 要： | 提出并设计制作了一种椭圆弧型过渡段有界波电磁脉冲模拟器，并与锥形平板过渡段有界波模拟器进行了对比。采用仿真和试验两种方法，仿真在电磁场仿真软件CST中开展，试验实际测量得到前沿上升时间约2 ns、脉宽约25 ns的双指数电场波形和前沿上升时间约2 ns、平顶持续约80 ns的阶跃型电场波形。仿真和试验结果表明：该模拟器有效削弱了前后过渡段与平行板段连接处的不连续性对场波形的影响。

| Abstract: | A bounded-wave simulator with ellipse-arc transitional section structure is proposed and designed. The electric field waveform in the simulator is simulated and compared with the tapered transitional section simulator by using the electromagnetic-field simulating software CST. The double exponential pulse with rise time 2 ns, full-width at half-maximum (FWHM) amplitude 25 ns and the step pulse with rise time 2 ns, duration about 80 ns are obtained in the experiment. And a comparison is carried out between the two simulators. The results of simulation and experiment both indicate that the bounded-wave simulator eliminates the interference effectively coming from the discontinuity at the junction of the transitional section and parallel-plate section. |
