Propagation of a Pulse Through One-dimensional Photonic Crystals Containing Negative Materials
光脉冲在一维负折射材料光子晶体中的传播

The transmission of pulses through photonic crystals containing negative materials is discussed.Through the numerical analysis of the transmitted electric field,it is foud that the propagation of a Gaussian short-pulse with its carrier frequency lying in the band gap of a photonic crystals containing negative-index materials through the photonic crystals is basically Gaussian distribution,and for the same of short-pulse through the traditional one-dimensional photonic crystals,the transmitted electric field is a distorted spectrum.When the negative-index materials is dispersive,the variance of the phase time versus the carrier frequency of pulse is discussed.
