On real-time method-of-moments analysis using graphics processing unit

We discuss the present-day limits of real-time MoM analysis using one graphics processing unit on a personal computer. A square plate scatterer with pulse-expansion MoM is used for illustration. The results show that for less than 0.3 s, which is considered as practically real-time, MoM analysis of problems with about 500 complex unknowns can be solved using simplest available CUDA GPU (8400 GS), and up to about 2500 unknowns can be solved using higher tier GPU (GTX 560).
