Paper Abstract

Decomposed into Gauβlets (Gaussian beamlets or “fat rays”), a diffracting wavefield can be propagated through an optical system by simple ray tracing. As an update to a 1990 ILDC presentation, the method’s progress since then is covered along with new comparisons against more precise solutions.
