摘要
针对传统矩量法(method of moment,MoM)几何建模复杂、计算量大等缺点,采用高阶矩量法和双线性表面技术对涂敷目标的电磁散射问题进行了研究。建立目标的双线性表面几何模型,基于等效原理建立表面电磁积分方程,以典型的完全涂敷目标为例,采用高阶矩量法进行仿真计算。计算结果表明,该方法不仅与传统MoM结果吻合,而且减少计算量和节省计算机内存。
As the conventional method of moment （MoM） has some disadvantages in geometrical modeling and computational work, the high order MoM and bilinear surface technology are used in studying the scattering electromagnetic characteristics of dielectrically coated conducting targets. Firstly, the geometrical structure of the target is approximated by bilinear surface technology. Then, surface integral equations are formed. Finally, simulation calculation to representative dielectrically completely coated targets is conducted. Compared the high order MoM results with the results of literatures, good agreement is found between them. At the same time, the high order MoM greatly decreases computational load and saves computer storage. This algorithm has some value in efficiently solving electromagnetic scattering （EM）problems of coated targets.
