Manipulation of visual tools that look small artificial china

The team of scientists led by Wei Xiang Jiang and Tie Cui from Southeast University in June, Nanjing, China, recently published a tool that can shrink the solid results of their studies. Innovation is published in the latest issue of the scientific journal Applied Physics Letters.

However, not physically shrink. "It can shrink the virtual objects", said Cui. Devices working at microwave frequencies can be deceiving radar and other electromagnetic detection equipment that makes potential to be applied by the military.

The scientists made use of metamaterial devices reducers are also used in the development of the invisibility cloak. In this tool, used to make eight metamaterial concentric rings each as high as 12 millimeters. Then they put an object, such as a spoon, in the middle of the ring.
When light waves spread out through instrument reducers, curved front wave and its wavelength is compressed. When the light reaches the center of the circle, so that the wavelength terdekompresi for people who look from the outside of the tool penyusut, light creates the illusion of objects manipulated by the same form as the real thing, only smaller.

"These devices are designed using transformation optics that make the object in real space and virtual space looks the same," said Cui. On their design tool, real objects are objects that are large while the smaller virtual objects.
The scientists were also explained, because the proportion of some object depends on its size, it means they made ​​reducers can display virtual objects that are small in reality does not exist.

In addition, the methods used to develop the appliance reducers can also be further developed to design and create the illusions that can be able to change some other parameters of an object.
