Wave packets in dispersive media: an approximation encompassing both main signal and precursors
Published online by Cambridge University Press: 13 March 2009
Abstract
The propagation of a linear wave packet in a generally dispersive, but non- absorbing, medium is considered. By an extension of the principle of stationary phase to higher inverse order in time, an approximation is derived that encompasses both the main signal propagating at the group speed, and the precursors that precede and follow it.
