%X The propagation property of electromagnetic solitons in the negative-index material with a nonlinear polarization is investigated numerically,and the influence of the controllable self-steeping resulted from the dispersive permeability of negative-index material on the propagation property of solitons is analyzed.It is shown that,like the positive self-steeping effect in an ordinary medium,the negative SS effect also leads to the asymmetry of soliton,the shift of soliton center,and the decay of higher-order solitons.The direction of the shift of soliton center is decided by the sign of self-steeping.Furthermore,to some extent,the shift of soliton center resulted from 3rd-order dispersion can be avoided through the use of controllable self-steeping effect,and the soliton can propagate along the propagation axis.
