摘要

提出了一种多能级快速物理光学(MLFPO)技术，以加速电大型涂层散射体散射场的计算。该方法基于二次补丁细分和多电平技术。首先，采用二次块而不是平面块来离散所考虑的散射体。因此，大大减少了贡献补丁的数量，从而使MLFPO方法的工作量大大低于传统的Gordon方法。其次，本文引入多电平技术，避免了直接从考虑的散射体中计算物理光学散射场，从而大大降低了算法的计算复杂度。最后，数值结果验证了基于二次块的MLFPO方法的准确性和有效性。

THE MULTILEVEL FAST PHYSICAL OPTICS METHOD FOR CALCULATING HIGH FREQUENCY SCATTERED FIELDS

The multilevel fast physical optics (MLFPO) is proposed to accelerate the computation of the fields scattered from electrically large coated scatterers. This method is based on the quadratic patch subdivision and the multilevel technology. First, the quadratic patches are employed rather than the planar patches to discretize the considered scatterer. Hence, the number of the contributing patches is cut dramatically, thus making the workload of the MLFPO method much lower than that of the traditional Gordon’s method. Next, the multilevel technology is introduced in this work to avoid calculating the physical optics scattered fields from the considered scatterer directly, so that the proposed algorithm can significantly reduce the computational complexity. Finally, numerical results have demonstrated the accuracy and efficiency of the MLFPO method based on the quadratic patches.
