利用超材料让光线、声音绕过物体传播,使物体达到隐形效果,这是“隐身”衣的原理。不久前,德国研究人员成功演示了超材料同样能影响热的传导。他们用铜和硅制造了一个“隐热”盘,铜是热的良导体,而所用的硅材料是一种不良导体。 The use of metamaterials to let light, sound around objects spread, so that the object to achieve invisible effect, which is “stealth ” clothing principle. Not long ago, German researchers successfully demonstrated that metamaterials can also affect the conduction of heat. They made a “heat-sensitive” disk of copper and silicon, which is a good conductor of heat, and the silicon material used is a poor conductor.
