现在，研究者们正在创造一种奇妙的实验室工程材料，它可以让几乎任何一种传播中的波绕过其遮蔽的物体。

Now researchers are creating laboratory-engineered wonder materials that can conceal objects from almost anything that travels as a wave.

捕捉过程是这样的，因为低频波可以传输到更远的距离，当它们遇到地下的空穴或其他物体反射回来的时候，已经距地面的接收装置很远了。

The catch is that because low-frequency waves can travel great distances, when they do bounce off cavities or objects underground, they often end up far from the detection equipment at the surface.

做这件斗篷的材料很特殊，能使包括雷达或光波在内的各种波遇到物体后发生偏转，就象溪流遇到光滑的石头那样。

Cloaking used special materials to deflect radar or light or other waves around an object, like water flowing around a smooth rock in a stream.
