Simulation of ultrashort pulse propagation using geometrical optics

Thomas Weigel, Gustav Schweiger, and Andreas OstendorfRecent extensions to the open-source Geometrical Optical Analysis Tool (GOAT) bring ultrashort pulse propagation into a geometrical-optics framework by incorporating phase and spectral effects, bridging the gap between efficient ray tracing and computationally-intensive full-wave electromagnetic ...
