中文摘要：
在非线性左手材料中,Kerr介质的磁化效应,使得等效磁导率与磁场强度呈非线性关系.利用等效磁导率和磁场强度的二阶近似关系,得到关于电场和磁场的耦合模型.基于这一模型,给出它的精确的亮、暗孤子解.
英文摘要：
In nonlinear left-handed materials,the relation of the effective magnetic permeability and the magnetic intensity is nonlinear due to the magnetization of Kerr medium.By using the second-order approximation for the effective magnetic permeability,the coupling model for electric and magnetic fields is introduced,and the exact bright and dark soliton pairs are obtained based on the model.
