高功率脉冲源的双锥负载,在调试过程中将辐射强电磁波,对周围电子设备造成严重干扰.论文采用时域有限差分(FDTD)法,对双锥天线的近场辐射过程进行模拟计算,考察双锥终端分别为开路、短路和连接电阻负载三种状态下的电磁辐射特性,证明用电阻线连接双锥终端,可以同时抑制终端反射和空间辐射,保护脉冲源自身和电子设备.最后给出实验室内关键位置处的电磁骚扰水平.

The biconical load of high-power pulser can radiate intense electromagnetic pulse(EMP)during debugging,which poses great threats to the nearby electronic systems.The Finite-Difference Time Domain(FDTD)method is utilized to investigate the radiation eharacteristics of the bicone at the open,short and loaded states.It is validated that the resistive lines connecting the terminals of the bicone can suppress both the reflection from the terminals and the radiation in the free space,then protect both the pulser itself and the nearby electronic systems.Finally the electromagnetic disturbance levels are presented at the key locations in the laboratory.
