More details Close

This research makes it possible to implement moment method algorithm in GPU which was ever required by using the super computer with the very expensive cost. The developed moment method algorithm takes into account the large scale numerical analysis with the dielectrics. Definitely, it is hopeful that our electromagnetic analysis of a large model and acceleration algorithm can be applied to a lot of larger scale applications, such as a new artificial electromagnetic materials, space power generation systems, and communication, scattering / radiation problems including people, cars, ships and planes, and so on
