新型“超材料”可使战斗机隐形

俄罗斯科学家研制出一种可使战斗机隐形的新材料,其拥有自然界中并不存在的属性,可以通过阻挡、吸收、增强甚至弯曲等方式来操控电磁波,从而使物体隐形,能广泛应用于新型武器的研制以及超级计算机设计等领域。发表在《物理评论》杂志上的研究结果称,这种新材料由俄罗斯国立工艺技术大学(NUST MISIS)和希腊克里特大学的研究人员合作开发。双方于2016年签订了合作备忘录,加强量子技术研究,共同资助包括“超材料”在内的最新研究。

该项目负责人阿列克谢·巴沙林解释说:“我们最新研制的‘超材料’由从普通钢铁上切削下来的一小块所谓超分子网格组成, 由于这种网格独特的形状和构造,使新‘超材料’拥有独一无二的属性,能用来制造可探测爆炸物和化学武器的超灵敏传感器。”

国立工艺技术大学发表声明指出,添加非线性半导体还可使这一“超材料”变成一种可调整的屏幕,使战斗机对无线电、红外线和其他波段的光线隐形。而且,新的“超材料”也能用于研制最新一代激光和量子计算机。

据悉,俄罗斯卫星通信公司(RSCC)和其他太空组织已表示对最新研究成果感兴趣。

A team of researchers at Moscow's National University of Science and Technology (NUST MISIS) have come up with a unique metamaterial which can make combat vehicles invisible, the authoritative scientific journal Physical Review wrote.

Metamaterial is a substance engineered to have a property that is not found in nature. It is capable of manipulating electromagnetic waves by blocking, absorbing, enhancing, or bending them to make things invisible.

Metamaterials can be widely used in the development of new types of weapons and the design of supercomputers where conventional electrical signals will make way for photonic ones.

The NUST MISIS team worked closely with colleagues from the University of Crete, Greece. In 2016 Russia and Greece signed a memorandum on cooperation in quantum technology research and joint financing of this work, including the study of metamaterials.“The experimental part of our research was the creation of a one-of-a-kind metamaterial consisting of a small flat grid of the so-called meta-molecules cut out from a solid piece of ordinary steel,” the project’s director Alexei Basharin was quoted as saying by the NUST MISIS press service.

Basharin said that thanks to the special shape and configuration of these cells the scientists managed to obtain metamaterial with absolutely unique properties. This metamaterial can be used to make supersensitive sensors to detect explosives and chemical weapons.

“An addition of a nonlinear semiconductor will turn the metamaterial into an adjustable screen for stealth technologies, which make fighting vehicles less visible  in radio, infrared and other bands,” the NUST MISIS press service said in a statement.

The newly obtained metamaterial can also become a vital element of the latest types of lasers and serve the basis for quantum computers.

“The Russian Satellite Communications Company (RSCC) and other space-related organizations have already shown interest in the new material,” the NUST MISIS statement said.
