摘要

对电子发射面设置问题进行了研究,给出了底入射腔体系统电磁脉冲模拟中电子发射面的实现方法,分析了侧入射腔体系统电磁脉冲模拟中电子发射面的特点,并利用虚拟发射面的方法实现了侧入射腔体系统电磁脉冲模拟中电子发射面的设置。结果显示,利用该方法可以较简洁地实现腔体系统电磁脉冲模拟中平面和曲面电子发射面的设置,发射面电子发射参数和时序符合物理规律。

Abstract

The setting method of electron emission boundary in cavity system generate electromagnetic pulse(SGEMP) simulation is researched. The electron emission boundary in bottom incidence cavity SGEMP simulation is introduced, and the peculiarity of the boundary in side incidence cavity SGEMP simulation is analyzed. By the employment of virtual-emission-surface, the electron emission boundary in side incidence cavity SGEMP simulation is realized. It is indicated that by using the method mentioned here one can achieve the electron emission boundary efficiently, both in flat and curved surface boundary condition, and the parameters and emission sequence of electron on the boundary obey the corresponding physical laws.
