Abstract :
In this paper, a Method of Moments with Higher-Order basis functions (HOBMoM), parallel implementation based on Message Passing Interface (MPI) and Out-of-Core technology (OOC) has been proposed to compute the Radar Cross Section (RCS) of an aircraft´s engine. The block-partitioned parallel scheme for the large dense MoM matrix is designed to achieve excellent load balancing and high parallel efficiency. Because of the bottleneck of the RAM limitation, the out-of-core technology is employed. Some numerical results demonstrate that the Higher-Order basis used in this paper is superior to the conventional RWG basis and is capable of solving various electrically large problems such as the computation of RCS.
