Electromagnetic pulse effect simulation research in the core part of certain AA Gun

摘要

The electromagnetic simulation principle based on MOM is introduced in this paper. The electromagnetic simulation research in the core part of certain type AA Gun is carried out. The simulation results are as follows: The resonance does not occur inside the controlling-box when the frequency of electromagnetic ware is low. The intensity of electromagnetic field of seams and holes is the highest in this condition. The resonance occurs inside the controlling-box when the frequency of electromagnetic wave is high. There are some key points with extraordinary high electromagnetic intensity. The electron devices located in these key points are given rise to serious electromagnetism coupling, which seriously influences the use of AA Gun, even results in the damage of AA Gun.
