Full-wave electromagnetic solutions of electrically large objects require large amounts of computer storage and CPU power. Therefore, full-wave techniques, such as the method of moments (MoM), are frequently hybridized with approximate methods like physical optics (PO). As a successful example of this approach, an efficient iterative MoM-PO (EI-MoM-PO) method, which effectively combines MoM and PO to reduce the computational time while providing acceptable accuracy, was proposed. In this paper, the multilevel fast multipole algorithm is employed to further increase the efficiency and accuracy of the EI-MoM-PO method. Numerical examples are presented to demonstrate the efficiency and accuracy of the proposed approach.
