Parallel hybrid Finite Difference Time Domain and Multilevel Fast Multipole Algorithm based on equivalent-principle

In this paper, based on equivalent-principle, a parallel hybrid Finite Difference Time Domain (FDTD) and Multilevel Fast Multipole Algorithm (MLFMA) is introduced to analyze the radiation characteristic of an airborne antenna array. The numerical convergence of results is achieved through several iterations. Numerical results show that it can greatly reduce the memory requirement and time consumption.
