Accurate evaluation of RCS on the structure of aircraft inlets

A parallel version of Method of Moments (MoM) with Higher-Order Basis functions (HOB-MoM) with the Out-of-Core technique (OOC) is proposed to compute the Radar Cross Section (RCS) of an aircraft with engine inlets in this paper. The block-partitioned parallel scheme for the large dense MoM matrix is designed to achieve excellent load balancing and high parallel efficiency. The OOC technology is employed to break through the random access memory (RAM) limitation. Some numerical results demonstrate that the higher-order basis used in this paper is superior to the conventional RWG basis and is suitable to solve various electrically large problems such as the computation of RCS.
