Solving radiation problem with P-FFT method on graphics processing units

In this paper, the surface-wire integral equation combined with the Precorrected-FFT method is used to solve antenna radiation problem. The code is further parallelized to harness the power of graphics processing units (GPUs). The parallel algorithm on GPU is described and the code flow is shown. Test result is given to demonstrate the correctness of the code and benchmark is conducted to show the great acceleration performance.
