Analysis of Electromagnetic Leakage of HPM Source Based on TWPE

In this paper, electromagnetic leakage distribution in a factory was analyzed. The high-power microwave (HPM) source will inevitably produce electromagnetic radiation when it works, in order to quickly obtain the leaked electromagnetic field distribution, the two-way parabolic equation (TWPE) algorithm was adopted. Through modeling and measurement, spatial field distribution of entire factory was computed finally. The results show that the electromagnetic leakage of the factory conforms to the relevant national safety standards. The whole modeling and calculation process may provide an effective means for assessing the electromagnetic environment around the HPM source.
