An electromagnetic scattering solver utilizing shooting and bouncing rays implemented on modern graphics cards

The shooting and bouncing rays (SBR) technique has proven to be a faster, accurate alternative to full-wave electromagnetic simulation algorithms for many applications. Despite their reduced complexity, SBR simulations still require tremendous computational power in order to solve many problems of interest. In my thesis, I present the results of my SBR computational acceleration efforts. Specifically, the two core processing bottlenecks of the SBR algorithm, ray tracing and waveform calculations, have been mapped to a graphical processing unit (GPU) architecture for faster execution. The highly optimized GPU demonstrates a tremendous performance increase over standard microprocessor-based solutions, enabling larger simulations to be performed in less time. My thesis work produced a GPU accelerated SBR simulator that exhibited a 10x speedup over existing solutions.
