negative refraction index

基本解释

What would a negative index of refraction look like?
如果折射率是负的,会发生什么事情?
Finally, the structure of single SRRA was improved by a quasi-Ω-like metallic pattern and a compound material with negative index of refraction was obtained.
对单金属环阵列结构进行了改进，得到了一种体现负折射率效应的准Ω结构的复合介质。
Back in 1968, Victor Veselago, a Russian physicist, reasoned that a material might be engineered to create a negative index of refraction and bend light waves more radically.
追溯到1968年，一位俄罗斯维克托·韦斯莱格（Victor Veselago）推理出，可能设计一种具有负折射率的材料，从而以更加非传统的形式使光线弯曲。
