In this article ,the band gap of a ID photonic crystal containing negative refraction materials was studied.

Negative refraction materials, first introduced as left-handed media by Veselago in the 1960s, usually possess both negative electric permittivityεand negative magnetic permeabilityμin a certain frequency band.

Compared with the fishnet NIMs of circular-shaped holes,these two structures can realize negative refraction at multi-frequency bands,and the resonance frequencies exhibit an obvious red-shift.

This paper focuses on a series of theoretical and experimental studies of the physical optics,such as the Goos-Hnchen shift,the FTIR phenomena,the negative refraction index,the superluminal experiments of THz rays,and the measurement of photon rest mass.

The new electromagnetic properties of negative index material such as converse Cerenkov radiation and converse Doppler effect,negative refraction index and perfect lens are analyzed and explained by using basic electromagnetic theory.

The paper introducs the history and research of negative refractive materials and simply analysis of negative index of refraction gives rise to the strange properties such as negative group velocity,negative refraction,perfect lens,inverse doppler effect and abnormal Cerenkov radiation.
