In this paper, a CUDA-enabled GPU accelerated implementation of Method of Moments (MoM) for solving three dimensional conducting body-wire problems is presented. The solution is based on the Mixed Potential Integral Equation (MPIE) discretized using Rao-Wilton-Glisson (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 8 times over the CPU implementation is demonstrated.
