The results show that the ultrashort pulse would be narrow in the normal dispersion if the parameter of second-order nonlinear dispersion was less than zero,and the effects of its was gradually changing with the propagation distance getting smaller and smaller,and the pulse would be width if the parameter of fake-quintic nonlinearity.
结果表明,在正常色散区,二阶非线性色散系数为负时使脉冲变窄,而且它对脉冲影响的程度是随着传输距离不断变化的,影响越来越小;赝五阶非线性系数为负时使脉冲展宽,但与二阶非线性色散项相比影响较小;而自陡系数取值的可正、可负出现了使脉冲在传输过程中其中心位置前后沿均可偏移的现象。
The influence of dispersive magnetic permeability on propagation of untrashort pulses in metamaterials is mainly in that it leads to the appearance of the pseudo-χ (5) , self-steepening (SS) and second-order nonlinear dispersion terms in the propagation equations.
结果表明,在反常色散情形,赝五阶非线性在异向介质的负折射区中增大了调制频谱的范围及增益值,这与常规正折射介质中出现的现象正好相反;自陡峭效应在异向介质中有可能为负值,但无论正负,也无论在正折射区还是负折射区,它都抑制调制不稳定性的产生;二阶非线性色散效应在正、负折射区中分别促进和抑制调制不稳定性的产生。
Further,we study the influence of the controllable self-steepening effect and the second-order nonlinear dispersion on the formation and propagation of dark solitons in metamaterials.
