Abstract
The propagation of Gunn layers (GL), i.e. the nonlinear waves of an el ectric charge distribution in a dissipative system, under the influenc e of random perturbations, which may be characterized as white Gaussia n noise, is considered. The average characteristics of the perturbed G Ls are analyzed and compared to those describing a ''random walk'' of kinks in a damped system [F.G. Bass, Yu.S. Kivshar, V.V. Konotop and Y u.A. Sinitsyn, Phys. Rep. 157 (1988) 63].
