中文摘要：

研究一维线性函数光子晶体的透射特性，分析不同周期数和光学厚度对电场分布的影响，得到一些不同于常规光子晶体结论，当介质层B和A折射率分布函数为线性增加时，线性函数光子晶体透射率可以远大于1；随着周期数N的增加，其电场强度最大值明显增加，通过改变周期数N就能改变光在函数光子晶体中的电场强度的放大倍数．该结论为光子晶体的制备和应用提供了理论方法和思路．

英文摘要：

This paper researches the transmissivity of the one dimensional linear function photonic crystals,and the effect of different period numbers and different optical thickness on the field intensity in photon crystals. Some new results different from the conventional photonic crystals are obtained. When the medium BandArefractive indexes distribution function for linear increase, transmissivity of linear function photonic crystal can be far greater than 1;with the increase of period numbers, the maximum value of electric field strength increases significantly;the change of period numbers can make the magni- fication of the function photonic crystal field change accordingly. Such results provide theoretical ap- proach and idea for photonic crystals preparation and applications.
