What would a negative index of refraction look like?
如果折射率是负的,会发生什么事情?

If water had a negative index of refraction, then a straw placed in a glass would appear to bend back under itself.
如果水具有负折射率，那么放在玻璃杯中的吸管似乎可能弯曲到自身下方。

They then cascaded the negative index medium with a positive refractive index medium so that the complete nanostructure behaved as one with an index of refraction of zero.
