| Abstract: | The scattering of a non linear wave packet as an envelope soli ton by a one-dimensional disordered system is studied. It is well known that in the linear limit the transmission coefficient decays exponentially with a characteristic localization length. We predict, using a simple independent scattering approach and soliton perturbation theory in the framework of the non linear Schrodinger equation, that strong nonlinearity above a certain threshold allows undistorted propagation of wave packets. |
