Abstract

The multilevel physical optics (MLPO) method is an effective method for performing the simulation of scattering patterns from a range of frequencies and aspect angles. However, the number of plane patches used to discretize the surfaces of the scatterers will increase with the frequency. Therefore, workloads of the domain decomposition and the calculation of the physical optics integral are too heavy. In order to improve efficiencies, this letter proposes the multilevel second-order physical optics (MLSO-PO) method, which combines the quadratic discretization with the multilevel technology. The workload of the domain decomposition will be reduced greatly, since there has been a decrease in the number of patches. Furthermore, we implement closed-form formulas with the complementary error function to avoid highly oscillatory phenomena. Numerical experiments are provided to benchmark the efficiencies of the MLSO-PO method.
