中文摘要：
本文研究了光子晶体周期堆栈的时候,输入波能够快速的衰减的条件下,一维光子晶体的传输特性。研究表明,当入射角一定时,光子晶体的填充率能够得到最好的禁带带宽和反射率:而随着入射角度的增加,光子晶体的反射率逐渐增大,反射效果更好,同时带隙宽度逐渐变大,而全能反射带宽逐渐变小,并向长波方向移动。与其它结构的光子晶体相比,这种条件下一维光子晶体利用很少的周期数,就可以得到99%以上的反射率和很宽的禁带宽度。
英文摘要：
Using the method of optimal design to discuss the optical transmission characteristics of one dimensional photonic crystals.The results indicate that when the angle of incidence is definite,we can get the best width of band gap and reflection in the case of the filling fraction of the optimal design,the reflection and the width of the omnidirectonal reflection band with the increment of the incidence angle increases gradually otherwise the width of the photonic band gap gets narrower.
