Research of optical properties of one-dimension photonic crystals constructed by positive-negative refractive materials

QI Jun-xuan; WEN Shuang-chun

Photonic crystals were the new artificial complex media during the last decades,however its transmission property might change a lot if new material with negative refraction index are inserted.The main properties of the band gap and dispersion structure of the one-dimensional photonic crystal,whose each period consisting of one layer of a usual material and one layer of negative refractive material,are studied based on Maxwell equation and Bloch theory.Our analysis results show it possible to make the band gap of the periodically-layered photonic crystals wider than the usual material,which offers a possibility to design photonic band gap structure with wide stop bands.
