Telegrapher’s equations with variable propagation speeds [PDF]
Physical Review E, 1994 All derivations of the one-dimensional telegraphers equation, based on the persistent random walk model, assume a constant speed of signal propagation. We generalize here the model to allow for a variable propagation speed and study several limiting cases in detail.
