Parallel computation of complex antennas around the coated object using hybrid higher-order MoM and PO technique

This paper presents a novel hybrid technique for analyzing complex antennas around the coated object, which is termed the iterative vector fields with Physical Optics (PO). A closed box is used to enclose the antenna and then the complex field vector components on the box´ surfaces can be obtained using Huygens principle. The equivalent electromagnetic currents on Huygens surface are computed by Higher-order Method of Moments (HOB-MoM) and the fields scattered from the coated platform are calculated by PO method. Moreover, the parallel technique based on Message Passing Interface (MPI) and Scalable Linear Algebra Package (ScaLAPACK) is employed to accelerate the computation, and good load balance and parallel efficiency are obtained under the proposed parallel scheme. Finally, some numerical examples are presented to validate and to show the effectiveness of the proposed method on solving the practical engineering problems.
