| 摘 要： | 在传统的二元一维光子晶体中,如果有一种材料在某一段频带范围内显示出负折射率特点,此光子晶体的色散特性肯定不同于传统的光子晶体.首先通过建立简单的模型推导出光波在光子晶体中传播的表达式,然后进行数值模拟和分析,并引入负折射率表达式,仿真得到这种光子晶体的色散图形.研究结果表明,该光子晶体在微波频段存在多个小的禁带,可以作为多通道滤波器.在高频带,当构成光子晶体的两种材料的厚度发生改变时,禁带的位置也会变化.

| Abstract: | If one kind of material in the traditional binary one-dimensional photonic crystal exhibits its negative refraction index in a certain frequency band,the dispersion characteristics of the photonic crystal are different from that of the traditional photonic crystal.First,a simple model is established to deduce the expression of light propagtion in a photonic crystal.Then,numerical simulation and analysis are conducted and the expression of negative refractive index is introduced.Through simulation,the disper... |
