Abstract

A parallelization approach of the finite element-boundary integral-multilevel fast multipole algorithm (FE-BI-MLFMA) is presented and implemented for scattering by large and deep coated cavities loaded with obstacles. Numerical experiments demonstrate the parallel efficiency of this parallelization approach. The capability of the parallel FE-BI-MLFMA is demonstrated by computing scattering by a big and deep brick cavity with 15λ×15λ×100λ. A three-layer meshing approach with the aid of commercial software 'ANSYS' is presented to facilitate the FE-BI-MLFMA to efficiently analyze cavities loaded with complex obstacles. Numerical examples of complex cavities are performed to validate the meshing approach. Comparisons of numerical results and measured data verify the accuracy of the FE-BI-MLFMA for complex cavities.
