摘要

本文旨在分析峰值电容内芯直径对电磁脉冲仿真双锥天线辐射场的影响。数值模拟结果表明，随着内芯直径的增大，在打开输出开关前，天线中心的辐射场振幅减小，打开输出开关后，距离天线中心3m处的观测点的辐射场振幅也有相同的规律。结果表明，为了提高EMP模拟器的幅值效率，电容器的内芯直径应尽可能小。

Influence of the Peaking Capacitor with Different Inner Core on the Radiating-field of a Biconical Antenna

The paper is aimed at analyzing the influence of the diameter of a peaking capacitor’s inner core on the radiating-field of a biconical antenna for EMP (Electromagnetic Pulse) simulation. Results of numerical simulation show that as the increase of the diameter of the inner core, the amplitude of the radiating-field in the center of the antenna decreases before the turn-on of the output switch, and after the turn-on of the output switch, the same law is discovered for radiating-field in the observation point 3m away from the center of the antenna. The results indicate that in order to improve the amplitude efficiency of the EMP simulator, the diameter of capacitor’s inner core should be as small as possible.
