Popis:	The attenuation of waves is due to dissipative effects of the medium in which they travel. We study waves amplification in a nonlinear transmission line by doping the line with negative nonlinear resistance. Modifying the cells of the line with this resistance, the propagation of waves is governed by a perturbed Korteveg–de Vries (KdV) equation. Analytical results and numerical simulation show that the attenuated wave recovers its amplitude on a short distance of the doped domain. It is also shown that the wave conserves its pulse form when crossing the amplification domain.
