Curvature(s) of a light wavefront in a weak gravitational field
arXiv:1001.2550
Abstract
The geometry of a light wavefront evolving from a flat wavefront under the action of weak gravity field in the 3-space associated to a post-Newtonian relativistic spacetime, is studied numerically by means of the ray tracing method.
