Abstract
We transform the problem of seeking the planar wave speed in general excita ble media into a cubically algbraic equation, thus we can find the explicit representation of the planar wave speed (in one-dimensional case, the trav eling wave speed) and dispersive relation. Especially for a few typical exc itable media, we give the formula for calculating the corresponding wave sp eed.
