负折射率
各位老师：大家好！我现在在准备关于负折射率方面的毕业论文，我看了一些有关方面的资料，还是没什么头绪，不知道该怎么开始，肯求各位老师予以指点，不胜感激！
最后，恭祝大家
新年吉祥平安

<P>google一下，好多的</P> 负折射率是针对某个特定的波段。不可能在全波段都是负的！ 负折射率的最大优点在于超透镜效应，可以很好的解决成像分辨率以及信息传输的精度。<img><br><br>提供你一些参考文献：<br><p:colorscheme colors="#ffffff,#000000,#808080,#000000,#00cc99,#3333cc,#ccccff,#b2b2b2">
