Adapting MoM with RWG basis functions to GPU technology using CUDA

In this letter, a CUDA-enabled graphics processing unit (GPU)-accelerated implementation of the method of moments (MoM) for solving three-dimensional conducting bodywire problems is presented. The solution is based on the mixed potential integral equation (MPIE) discretized using RaoWiltonGlisson (RWG) basis functions. The CUDA environment is employed to port a single-CPU sequential code to the parallel GPU platform, and some relevant issues are discussed. Numerical results are given for a helical antenna with a cylindrical cup reflector. The measured speedup of about eight times over the CPU implementation is demonstrated.
