The constitution, primary technique parameters and the transmission line structure of the EMP simulator are introduced in this paper. The transmission and spatial distribution of the electric-field were simulated numerically by Finite Difference-Time Domain method (FDTD). The double-exponential function is used as exciting source and the spatial electric-field distribution is obtained. The effect of the terminal impedance matching impedance on the electric-field distribution is also presented. The electric-field integral along the center line of the simulator is implemented to study the radiation efficiency of the transmission line and the phase spatial distribution of the frequency-domain components of the pulse sign. The simulated and measured results show that the transmission line electromagnetic pulse simulator has symmetrical electric-field distribution, high radiation efficiency and uniform phase spatial distribution of frequency-domain spectral components. The measured results agree well with the simulated ones. |
