摘要
首先分析了二维电磁散射问题的有限元算法理论,编写了相应计算程序;然后对一布置有两铆钉的二维SRAM蒙皮模型在铆钉间距为20、40和60mm情况下计算分析了铆钉间距对其隐身性能的影响,结果显示铆钉间距越大,蒙皮结构的隐身性能越好。
The theory of finite element method for solving 2-D electromagnetic scattering problems is analyzed and the programs are compiled. For a 2-D SRAM skin model with two rivets, its stealth properties under different rivets' spaces (space=20,40 and 60mm, respectively) are calculated by using these programs and the influences are studied. The results show that the bigger the rivets' space, the better the stealth property of the skin model.
