摘　　要：异向介质材料是由人工设计构造的、具有特异电磁特性的材料。其中同时具有负的介电常数ε及磁导率μ的称为左手材料或双负材料;仅有负的介电常数ε或负的磁导率μ的称为单负材料。本文介绍了实现异向介质材料及其非线性特性的方法,重点综述了异向介质材料中SH产生、光孤子传输、波混频效应等方面的研究进展。A novel class of artificial materials, possessing particular electromagnetic properties, is defined as metamaterials, in which materials with simultaneously negative dielectric permittivity and magnetic permeability are called left-handed metamaterials or double negative materials and only with negative dielectric permittivity or magnetic permeability called single negative materials. Methods for realizing metamaterials and nonlinear left-handed metamaterials are introduced. In particular, research progress for second-harmonic generation, propagation of soliton, wave mixing effect in metamaterials is presented.
