单翼圆柱电磁散射的混合解

本文利用混合法分析和计算了单翼理想导电圆柱远场散射。这种混合法应用了物理光学近似（ＰＯ）、ＦＯＣＫ理论、物理绕射理论（ＰＴＤ）、几何绕射理论（ＧＴＤ）和矩量法。计算结果与矩量法和Ｍｉｃｈｅａｌｉ的计算和测量结果一致。与Ｍｉｃｈｅａｌｉ的方法相比，混合法对于任意尺寸的圆柱半径与翼宽和任意的入射角都适用。

Hybrid Solution for EM Scattering from a Finned Cylinder

The scattered far field from a perfectly conducting circular cylinder with a fin is calculated using a hybrid method which combines Physical Optical(PO) ,FOCK theory ,Physical Theory of Diffraction(PTD) , Geomtrical Theory of Diffraction(GTD) with Moment of method(MM) . Results are compared to those of MM and those of Micheali's theoretical calculation and measured data,and quite good agreement is obtained. In comparison to Micheali's theoretical analysis,the hybrid method is valid for any magnitudes of cylinder radius and the fin width,and for any incident angle.
