摘　　要：光与超常介质相互作用时,光的磁场也变得很重要。超常介质的色散磁导率导致光与超常介质的非线性相互作用呈现出许多新特性。总结了超常介质中二阶非线性光学现象的国内外研究进展,报道了在三阶非线性超常介质中光的传输特性方面的研究结果,包括传输模型的建立、调制不稳定性、孤子和自聚焦现象等。When light field interacts with metamaterials, both the electric field and the magnetic field must be considered. The dispersive permeability of metamaterials induces many new characteristics under the nonlinear interaction between light field and metamaterials. The research progresses on the second-order nonlinear optical phenomena are briefly described, and some research results on the propagation characteristics of electromagnetic waves in the metamaterials with third order nonlinear optical responses are specially presented, such as the establishment of the propagation model, the results for modulation instabilities, solitons, self-focusing.
