Abstract
In the context of wave propagation, wave dispersion is typically associated with properties of the propagation medium. Here we demonstrate the influence of forcing (over a spatially extended region) on the phase and group velocities of a wave field in both dispersive and nondispersive media. The influence of forcing on observed wave dispersion is relevant because it provides a means for overcoming the effects of material dispersion (such as the spreading of wave packets) in a broad range of wave physics, from electromagnetism to acoustics.
