According to foreign media reports, Israeli scientists developed a cloak-type device that can scatter the light shining on an object so that it can not be detected. It can be regarded as the legendary invisible clothing. "Israeli Ben Gurion University scientists are working on the concept of product development, so that objects really become a reality invisible.If successful, the technology can be used in the military, for the existing radar absorbing coating, optical camouflage technology, infrared detection technology, electromagnetic waves Decentralized technology to provide additional.
Scientists have proposed a new method to make objects invisible.The picture shows the meta-material invisible clothing concept map.
Dr Alina Karabchevsky, the lead author of the study, said: 'We have demonstrated through research that an optical chip allows the light around the cloak to be bent so that the light does not Interacts with the object to stealth the object.
The study shows that placing an object on a surface made of this 'cloak' material causes the surrounding light to be scattered and thus 'stealth' in the eyes of the naked eye, yet still detectable by infrared sensors or radars.
Based on the research of 'metamaterials', this method of invisibility of an object utilizes and controls light by observing the interaction of light with an object, which is reflected by the object when it is irradiated by ordinary light, while the 'metamaterial' You can make the light refraction.
In 2015, US Department of Energy researchers used the material to create an invisible 'skin cloak' that could be adapted to the size of the object and made it undetectable, the size of which currently can only be described microscopically, but scientists Efforts have been made to develop larger versions for larger objects.
In the following study, scientists will use X-ray, infrared and visible light to experiment and continue to explore the mysteries of the interaction between light and objects.
