Scientists have created metamaterials to guide rays of light around tiny, two-dimensional objects.

科学家已经制造出超材料能引导光线绕过微小的的二维物体。

The advent of " metamaterials" provides a new solution for the perfect invisibility of any electromagnetic wave.

“超材料”的出现为任何电磁波的完美隐形提供了新的解决方案。

But a metamaterial—a clever arrangement of thin brass plates bent into tiny maze-like shapes—has just the right properties.

但是有一种超材料，巧妙设计弯曲成小迷宫形状般的的薄黄铜片就具有了上述适合的属性。

The way light travels through the four dimensions of space-time is mathematically akin to how it moves through “metamaterial”.

从数学的角度看，光穿越四维空间的方式与它穿透“超材料”的方式很接近。

Some use acoustic metamaterials—a class of materials engineered to have surprising effects not commonly found in nature.

其中一些人使用声学超材料——一类经过设计可以产生自然界中不常见的惊人效果的材料。

Two years ago Dr Smolyaninov suggested an experiment with various metamaterials, corresponding to universes with different properties lashed together into a home-brewed multiverse.

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。

A team of researchers created a metamaterial to do this, which wraps around a three-dimensional object, just like a cloak would.

一组研究人员创造了一种超材料来做到这一点， 它包裹着一个三维物体，就像斗篷一样。

" In the future, with the gradual maturity of technology and 'metamaterials', the 'invisibility 'fantasy in science fiction works will gradually come to reality."

“未来，随着技术和‘超材料’的逐渐成熟，科幻作品中的‘隐形’幻想将逐渐成为现实。”

Depending on the outfit's function, it could contain carbon nanotubes, programmable matter, metamaterials, claytronics, or any number of other useful materials.

根据装备的功能，它可能包含碳纳米管、可编程物质、超材料、粘土电子学或任何其他有用的材料。

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, and suspended 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。

See, to do this, we need to use something called a metamaterial -- which is a material whose structure makes it exhibit properties that don't occur naturally -- like, invisibility, for example!

看， 要做到这一点， 我们需要使用一种叫做超材料的东西—— 这种材料的结构使其表现出不会自然发生的特性— —例如， 隐形！

In principle, then, metamaterials ought to be able to mimic how light moves not just through the space-time scientists on Earth are familiar with, but also other possible space-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。
