The propagation of a soliton pulse towards a finite potential barrier is examined, and it is found that in certain circumstances, depending on the ratio of soliton amplitude to barrier height, the soliton can tunnel through the barrier in a lossless manner. It is suggested that the phenomenon of barrier penetration by nonlinear pulses may have widespread application.
