| 摘 要： | 采用矩量法(MoM)结合阻抗边界条件研究了二维无限长任意形状截面非均匀各向异性阻抗柱体的电磁散射特性。散射场通过Stratton-Chu电场积分方程、电流连续性方程和二维格林函数予以求解。当柱体截面矢径的模等于恒定值时,目标退化为二维无限长圆柱,提出的计算方法仍然有效。计算得到的散射宽度结果与解析法、物理光学法(PO)的结果进行了比较,吻合良好。

| Abstract: | The electromagnetic scattering from inhomogeneous anisotropic impedance cylinder of arbitrary shape,which the surface satisfies most general impedance boundary,is investigated by Method of Moments(MoM).The scattered field is calculated using the electric field integral equation of Stratton-Chu,current continuity equation and two-dimensional Green's function.Once the radius of the cylinder is equal to a constant value,the proposed method is still valid.Obtained scattering width results are compared with thos... |
