Electromagnetic Simulations via Parallel Computing: an Application Using Scale Changing Technique of Passive Planar Reflectarrays in Grid Environment

International audienceElectromagnetic simulation continues to be the primary method by which engineers and researchers analyze and design circuits and systems. Nowadays, the complexification related to the rise of microwaves circuits results in the coexistence of several scales in the same circuit and in the appearance of important dimensions ratios. As the dimensions of modern Electromagnetic circuits continue to shrink, the fabrication and parametric testing of such structures have become more challenging. Increasing market pressures are driving engineers and researchers to minimize the time-to-the-market. So more efficient simulation strategies to accelerate the simulation process are required. Parallel and distributed simulation approaches seem to be a promising approach in this direction. With the growing incidence of computer modeling and simulation, the scope of this paper is to show that parallel simulation of multi-scale models can achieve several orders of magnitude speedup. When mapped onto distributed memory multicomputer systems like Computational Grid, additional speedup is obtained
