TRAVELING WAVE PROPAGATION IN A ONE-DIMENSIONAL FLUCTUATING MEDIUM

We investigate the one-dimensional motion of a traveling wave in a fluctuating medium. Two cases are studied; namely, fluctuating barriers with memory and continuously fluctuating medium. We have shown that as a result of the combination of noise and the spreading dynamics associated with traveling wave propagation, a signal propagates faster, even for values of coupling greater than the critical value associated with the propagation failure phenomena.
