Domain Decomposition Method: A Rigorous Algorithm for the Full-wave Analysis of Three-dimensional Microwave Structures

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.
