abstract

  • An efficient parallel hybrid solver consisting of the method of moments (MoM) with higher-order basis functions (HOBs) and physical optics (PO) is proposed for the analysis of complicated phased array antennas on
    electrically very large platforms. The higher-order MoM is hybridized
    with PO by iterating the MoM voltage matrix. The block-partitioned
    scheme for the large dense MoM matrix combined with the process-cyclic
    scheme for the PO discretized triangles is designed based on message
    passing interface (MPI). The parallel method is able to achieve
    excellent load balance and high parallel efficiency, and provides a
    solution with reasonable accuracy for solution of large on-board antenna
    problems. Numerical examples are presented to demonstrate that the
    proposed method can efficiently handle challenging realistic problems
    with a maximum dimension greater than 1000 wavelengths.
