Summary:
The keys to electromagnetic simulation of arbitrary configuration of conducting surfaces by method of moments (MoM) are filling of impedance matrix elements and solving of linear equations. A CUDA (Compute Unified Device Architecture) enabled graphics processing unit (GPU) launched by NVIDIA company to accelerate implementation of the fast filling of impedance matrix in MoM based on Rao-Wilton-Glisson (RWG) basis functions was presented. Parallel LU decomposition method is applied for the solving of linear equations, and a parallel method looping over squares is proposed in CUDA parallel platform, furthermore. The GPU numerical results for a usercreated benchmark structures are checked with comparison to CPU results. A noticeable speedup of the filling of impedance matrix (hundreds times) and solving of linear equations (about 10 times) is achieved due to the employing of GPU.
