摘要： 提出了三维微波结构的全波区域分裂算法.和其他方法相比,该算法可以大幅度地降低计算规模和计算的复杂性.文中详细讨论了不重叠型区域分裂法及其在差分格式下的实现,并利用差分格式下的区域分裂法计算了矩形波导内部三维分层结构和多层微带贴片天线的散射参数.所得结果和直接采用FDFD所得结果几乎完全吻合,证明了算法的正确性和有效性.

Abstract: In this paper, a full-wave domain decomposition method is presented for the analysis of three-dimensional microwave structures. Compared with other methods, it can greatly reduce the computing complexity and resource requirements for splitting the problem into finite independently sub-problems. The paper discusses in detail the implementation of the method in combination with FDFD method. The scattering parameters of a multilayered structure embeded in rectangular waveguide and a multilayered aperture-coupled antenna are analyzed by using the DDM. The complete agreement between our method and original FDFD method demonstrates the validity and flexibility of the method.

Key words: domain decomposition, full-wave analysis, three-dimensional structures, finite difference frequency domain
