A GPU Acceleration Method for Direct Solutions of Electric Field Integral Equations

The method of moments (MoM) as a traditional numerical method has been widely recognized and used in solving electromagnetic integral equations. As the scale of solved problems increases, the computational costs will rise significantly, often preventing it from a direct use. This necessitates the integration of acceleration techniques by either software or hardware. The hardware acceleration is mainly achieved through the central processing unit (CPU) or graphics processing unit (GPU). This paper proposes a GPU acceleration method for the direct solution of electric field integral equations (EFIEs) by the method of moments (MoM). Numerical examples show that the proposed method can be approximately 10 times faster than the acceleration of a state-of-art multicore CPU with an OpenMP parallelism.
