FE-BI-MLFMA Combined with FETI for Accurate and Fast Computation of Scattering by Large-Scale Finite Array Structure

摘要：

　　To effectively solve the electromagnetic scattering problem of large-scale finite array structure, a non-overlapping domain decomposition method(DDM), the dual-primal finite element tearing and interconnecting method(FETI-DP), is applied to the hybrid finite element-boundary integral-multilevel fast multipole algorithm method(FE-BI-MLFMA).The formula of near scattering field is deduced by equivalent electric and magnetic current.Then, the Generalized Radar Cross Section(GRCS) in near scattering region is calculated by the near scattering field.The numerical performance of the proposed method is demonstrated by calculating a patch antenna arrays scattering.
