To properly model inherent correlations induced by the scattering environments, electromagnetic propagation will be directly calculated with respect to physical distributions of surface and volume scattering material at multiple frequencies simultaneously. Because much of the calculation satisfies the conditions of symmetric data parallelism, the simulation will be developed to take advantage of Graphics Processor Units (GPU). The Phase I Base Plan goal is to conduct a feasibility and performance study of the applicabilty of a GPU-based propagation solution. We will select a set of physics-based calculations to implement on a GPU platform to demonstrate our approach and measure their relative performance gains over their CPU counterparts. Under a Phase I Option Plan we propose to develop a demonstration application that applies one or more scattering effects to a signal propagated between a moving source and receiver pair. Benefits: Rapid calculation of RF propagation and scattering effects in complex environments. Commercial applications include cell phone and broadband coverage modeling. Return
