Paper Abstract

In dispersive wave propagation, the standard stationary phase approximation to the wave is accurate in the asymptotic regime. Typically the calculation of the stationary points is taken to depend only on the dispersion relation. We examine the effects of including the spatial phase of the initial wave as well in the calculation and show that doing so can improve the approximation.
