| A Full 3-D Parallel EM Simulation Software Package |
| |
GEMS is a 3-D high performance parallel EM simulation package. GEMS combines many cutting-edge techniques to realize the high performnace that are suitable for solving general EM problem simulation such as electrically extremely large and complex problems such as antenna arrays, vehicle antenna, packaging problems, complex antennas, microwave circuits and devices, bioeletromagnetic problems, EMC and EMI problems. Compared to other software packages, GEMS has completely solved the technical bottlenecks in the numerical methods and memory limitation, and can be used to efficiently simulate large and complex problems.
