斜入射HEMP近地面电磁环境特性研究
A Study on Near-surface Electromagnetic Environment Characteristics of HEMP with Oblique Incidence
摘要
Abstract
High-altitude electromagnetic pulse (HEMP) has the characteristics of a wide coverage and high peak field strength, which poses a serious threat to the electronic devices. But the current HEMP standards include only the general wave characteristics in the free space, so the electromagnetic environmental characteristics near the ground induced by the HEMP incident plane wave oblique to the ground are studied in the paper, and the electromagnetic environmental parameters are calculated. The results show that, in the case of vertical polarization plane wave, the amplitude of horizontal field becomes smaller and pulse width becomes narrower when the incidence angle increases, but the ones of vertical field are just the opposite, and in the case of horizontal polarization plane wave, it is found that the changes of total-field characteristics in the lower position are more prominent than the ones in the higher position with the incidence angle changes.关键词
