时空也同样可以改变光的方向,改变方式取决于这个空间质量的分配方式。
In principle, then, metamaterials ought to be able to mimic how light moves not justthrough the space-time scientists on Earth are familiar with, but also other possiblespace-times to which they do not, and never will, have access.
原则上讲,超材料应该不仅能够模拟地球科学家们熟悉的光波穿越时空,而且可以模拟光穿越其它可能存在的,地球科学家们无法触及,也可能永远无法打开的时空。
Two years ago Dr Smolyaninov suggested an experiment with various metamaterials,corresponding to universes with different properties lashed together into a home-brewedmultiverse.
两年前,斯莫利亚尼诺夫曾建议用不同的超材料进行试验,相当于把拥有各种特性的宇宙集中到了自家创造的宇宙中。
In a paper to be published inOptics Express, he and his colleagues report that they havesucceeded.
他和他的同事在光学快报上发表了一篇论文,称他们的试验取得了成功。
Rather than fine-tune metamaterial to exact specifications, which is finicky and expensive,the researchers used nanoparticles of cobalt, which are relatively easy to get hold of, andsuspended them in kerosene.
研究者并没有对超材料的具体规格进行微调,因为这样既繁杂又增加成本,他们使用了钴的纳米粒子,这个相对而言容易得到,可以把它们暂时存放在煤油中。
