GEMS

GEMS® is a general purpose electromagnetic simulation software which includes several electromagnetic (EM) simulation solvers. GEMS comprises high-performance parallel Integral Equation solvers such as the Method of Moments (MOM) and the Multilevel Fast Multipole Algorithm (MLFMA). GEMS also offers High Frequency Electromagnetic solvers utilizing Physical Optics (PO), Physical Theory of Diffraction (PTD) and Shooting and Bouncing Rays (SBR) methods for high frequency problems such as scattering from electrically large structures.
