[交流] 新型材料能改道光线让隐形人成真

科学家已经制造了2种可让光线改道的新型材料,向隐形半蓬迈进了第一步。其中一种办法是使用金属鱼网层来反转光线的方向,而另一方法则是使用微小的银线来达到这一目的,且二者都是纳米级的。

Invisibility shields one step closer with new metamaterials that bend light backwards

By Sarah Yang, Media Relations | 11 August 2008

BERKELEY – Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered computers, and, to the delight of science-fiction and fantasy buffs, cloaking devices that could render objects invisible to the human eye.

Two breakthroughs in the development of metamaterials - composite materials with extraordinary capabilities to bend electromagnetic waves - are reported separately this week in the Aug. 13 advanced online issue of Nature, and in the Aug. 15 issue of Science.
