摘要：

针对几何结构及波端口激励源对称的大型目标，给出了高阶矩量法结合波端口理论的对称性分析方法. 结合并行核外计算技术，分析了大型波导窄边缝隙阵列的辐射特性．数值结果表明，利用波导缝隙阵列的几何结构对称性结合波端口的对称性，能够在保证算法精度的同时大幅度降低矩量法的内存需求和计算时间．

关键词: 高阶矩量法, 波端口, 对称性, 大型波导缝隙阵

Abstract:

Focusing on the symmetry of the geometric structure and wave port excitation, a symmetric analysis method utilizing the combination of the higher-order MoM and wave port theory is proposed. With the help of the parallel out-of-core computing technique, the radiation characteristics of a large-scale narrow slotted waveguide array are simulated. Numerical results show that the using the wave port and geometric symmetry can significantly reduce the requirement of memory and computing time while maintaining the same precision and accuracy.

Key words: higher-order MoM, wave port, symmetry, large waveguide slotted array
