Abstract

To simulate the source region electromagnetic pulse, a composite system was constructed by spatially combining a magnetic field coil with a bounded-wave simulator. This system can support the electromagnetic environmental effect tests that have both a pulsed magnetic field and pulsed electric field. However, the simulation results show that the magnetic field coil may cause electric field waveform distortion in the parallel section of the bounded-wave simulator. To explain the mechanism of electric field waveform distortion, a viewpoint was put forward that the spatial interaction relationships between the external magnetic field coil and the upper and lower plates of the bounded-wave simulator can be represented by three equivalent capacitors. In addition, the asynchronism of electric field changes was due to the charge-discharge property of the upper and lower capacitor on the intermediate capacitor. Furthermore, a circuit model based on these equivalent capacitors and inductor was established. The calculation results based on the circuit simulation software LTspice showed that, the voltage waveforms of the equivalent capacitors can be consistent with the electric field waveforms in the corresponding spatial region. These results verify the correctness of the equivalent capacitors and the circuit model proposed in this paper.
