摘　　要：负折射材料是近年来研究人员关注的新型材料,与常规材料相比,它有许多非寻常的表现,特别是光的折射.用惠更斯原理解释了负折射材料的折射规律,并分析了负折射材料制作的一些常用光学元件与传统材料制作的相应光学元件的不同作用.The negative refractive material is receiving much attention recently because of its many peculiar features, especially the anomalous refraction, compared with the regular material. A detailed explanation of the anomalous refraction in material with a negative refractive index using the Huygens principle is presented. The differences of the design of optical devices of the negative refractive material and that of regular material are also analyzed.
