双翼金属圆柱体散射场的整体计算

Global solution of scattering field of a metal cylinder with both wings

本文利用keller的几何绕射理论(GTD)推求出双翼金属圆柱体散射场高频快收敛整体解,弥补了传统分离解(把系统分解为一个金属圆柱和两个金属半平面,分别求解再简单迭加)的不足之处。最后,给出了整体解和分离解的散射电场的模值数值计算结果。

This paper works out the global solution of scattering field of a metal cylinder with both wings by u-sing Keller' s GTD. The solution converges rapidly when the frequency of wave is high enough. It overcomes the drawback of traditional parting solution. Finally the digital calculation result of scattering field of both solutions is given.
