  • A large scale low-profile traveling-wave narrow-wall slotted waveguide array with 2160 slots is analyzed by parallel method of moments (MoM) out-of-core solver based on the higher order basis functions (HOBs). Its
    accuracy is validated through comparison with the finite element method
    (FEM) adopted in the commercial software Ansoft HFSS. An out-of-core
    two-dimensional block-cyclic distribution scheme for the large dense
    full matrix filling and an out-of-core LU (lower/upper) decomposition
    matrix equation solver are utilized under the message passing interface
    (MPI). Numerical results are shown to demonstrate the memory cost
    effectiveness, time efficiency of the proposed method and its
    applicability. The method presented in this paper is able to solve
    challenging realistic problems in large scale.
