Turn beam?New processes can make artificial materials completely invisible

Science Fiction Network June 14th (Wang Ziyu) In the movie "Harry Potter", an invisible cape appeared, and others would not see you when others. Of course, this is just a scene in science fiction movies. But recently, scientists have developed a new type of process that can make artificial materials transparent and even completely invisible.

According to the "Scientific Progress" magazine, the scientists of Rostoch University and the University of Vienna University of Technology have cooperated with a material that can be invisible. It is reported that researchers use tritinal dioxide, ultra -materials, ultra -thin films and electronics materials to create invisible capes. It can transmit light signals through accurate adjustment of energy flow without generating any distortion.

Scientists said that when light spreads in an uneven medium, it forms scattering. The scattering will transform the compact orientation beam into a beam, and the micro density distribution of the material determines the specific details of the scatter. In addition, the beam attenuation caused by absorption seems to have a great reaction to the task of improving signal transmission.

In the experiment, scientists reappeared and observed the micro -interaction between the optical signal and the newly developed active materials developed by the optical fiber network. They found that if they want to achieve invisibility, it is not enough to prevent scattering, and the light waves must appear at all behind it. To this end, scientists construct the formula of the material through another way, that is, when the beam is passed, it seems that the material does not exist in the space it it occupies.

The discovery of this new technology provides a new method for the active and fine -tuning of the sensitive optical system. In addition, it is also very widely used in sensors, optical encryption and security data transmission, and espionage and military.
