harry potter inspired invisibility cloak pioneered by scientists - polycarbonate film
In the fictional world of Harry Potter, people usually find cloaks, but researchers in the United States claim they have created cloaks.
The cloak is only a few millimeters thick, but works under the microwave, making 3D items invisible from all directions.
Researchers at the University of Texas published their findings in the New Journal of Physics, saying the cloak consists of 0.
Layer 15mm is called metascreen.
This cloak is made up of copper strips attached to a flexible polycarbonate film, which scientists say can hide a 18 cm cylindrical rod.
Professor Andrea Aru, one of the authors of the study, said, "when the cloak and the scattering field interference on the object, they offset each other, at all viewing angles, the overall effect is transparent and invisible.
"People want this cloak to work under visible light.
"In principle, this technology can also be used to invisible light," Professor Alu said . ".
