提出了一种基于有限元法（FEM）和矩量法（MoM）混合的高阶区域分解（DD）方法，用于天线和散射体的三维建模。该方法基于曲面等价定理，在全局无界矩量法环境下实现了多个有限元域。所提出的分析的3-D和二维（2-D）有限周期阵列的非均匀介质散射体表现出优良的精度，收敛性，和效率的新FEM-MoM-DD技术，并大幅减少内存需求和计算时间相比，高阶MoM解决方案。
A novel higher order domain decomposition (DD) method based on a hybridization of the finite element method (FEM) and method of moments (MoM) is proposed for three-dimensional (3-D) modeling of antennas and scatterers. The method implements multiple FEM domains within a global unbounded MoM environment, based on the surface equivalence theorem. The presented analyses of 3-D and two-dimensional (2-D) finite periodic arrays of inhomogeneous dielectric scatterers demonstrate excellent accuracy, convergence, and efficiency of the new FEM-MoM-DD technique, and a substantial reduction in the memory requirements and computational time when compared to the higher order MoM solution.
