研究了含有负折射率缺陷的光子晶体中的局域缺陷模。利用传输矩阵方法计算了含有3个负折射率缺陷的一维光子晶体的透射谱，讨论了缺陷间的相互作用对缺陷模的影响。与正折射率缺陷情形相比较，负折射率缺陷间的相互作用对缺陷模的影响更大，局域模谱线更宽。

The local defect modes is investigated in photonic crystals with negative refractive index structural defects. Using the transfer-matrix-method simulation,the transmission spectrum in such one dimensional(1-D)systems including three defects is calculated,and the influence of the interaction between defects on defect modes is discussed. Compared with the case of positive refractive index structural defects,the influence of the interaction between defects on defect modes is stronger,the spectrum-width of defect mode is broader.
