摘要 将基于平面片的迭代物理光学(IPO)方法推广到曲面片上,发展了基于曲面片的迭代物理光学(CIPO)方法。利用CIPO方法计算分析了薄层天线罩和罩内散射体之间的电磁耦合作用。研究表明:同基于三角面片的IPO方法相比,CIPO方法对于表面曲率较大的目标可获得更高的计算速度和精度。 In this paper, the iterative physical optics （IPO） method is generalized from planar to curved surface patches, i. e. , the curved iterative physical optics （CIPO） method is developed. The electromagnetic （EM） coupling of thin-layer radome and scatterer under the radome is calculated and analyzed. It is shown that compared with the IPO method on planar triangular patches, for target surface with relatively larger curvature, higher calculation speed and accuracy can be obtained when the CIPO method is adopted.
