摘要：
An efficient hybrid technique that combines the characteristic basis function method (CBFM) and the finite element method (FEM) is presented for analyzing the scattering of large-scale array structures which may be dielectrics or metal objects. By utilizing the hybrid method, the whole array structures are divided into several blocks, and a set of the new characteristic basis functions (CBFs) independent of the incidence are generated. Furthermore, the singular value decomposition (SVD) leads to a significant reduced matrix. Numerical results are provided to demonstrate the efficiency and accuracy of the method.
