Advanced features to enhance the FDTD method in GEMS simulation software package

In this paper, we present the hardware acceleration technique to accelerate GEMS that is based on the parallel conformal FDTD method. This hardware acceleration technique uses the existing CPUs regardless Intel or AMD to speed up the GEMS EM simulation. Using the modern Intel or AMD CPUS, we can speed up the GEMS simulation up to 8 times and this performance is based on the existing optimized FDTD code. In addition, the conformal surface current distribution in the GEMS software package can significantly improve the performance of existing FDTD method for the radiation and scattering problems. The conformal current distributions on the large PEC structures such as aircrafts vehicles and vehicle are calculated to validate the new futures in GEMS.
