Abstract :
In this letter, a CUDA-enabled graphics processing unit (GPU) accelerated implementation of the method of moments (MoM) for electromagnetic simulation of wire-grid models of arbitrary configurations of conducting surfaces and wires is presented. The solution based on the frequency-domain electric field integral equation (EFIE) discretized using piecewise-linear (triangular) functions for expansion and testing is considered. Some issues pertinent to porting a single-CPU sequential code to an inherently parallel GPU platform are addressed. The GPU numerical results for a user-created benchmark structure are backed up with comparison to CPU results. A noticeable speedup (about 6×) of the overall MoM simulation is achieved due to employing GPU.
