All it requires is a clever handling of our views.
As their name implies, cloaks are devices that cover objects to make them appear indiscernible.
But one of the drawbacks of cloaking devices is that they are normally bulky.
In this study, we prove that we can use a thin single-layer sheet for cloaking.
Their hide, the researchers say, also overcomes another basic hitch of existing cloaking devices, being lossy.
It wont lose any intensity of the light that it reflects, said Kante.
Many cloaks are lossy because they are made with metal particles, which absorb light.
This is what happens when you use a lossy cloaking gear, says Kante.
What we have achieved in this study is a lossless cloak.
It wont lose any strength of the light that it reflects.
This cloaking gear basically fools the observer into thinking that theres a flat surface, said Kante.
The study was published in the journal Progress in Electromagnetics Research.
The researchers used Computer-Aided Design software with electromagnetic model to design and optimize the cloak.
Our computer simulations show how our cloaking gadget would behave in reality.
Doing whatever we want with light waves is really electrifying, says Kante.
Using this technology, we can do more than make things invisible.
We also expect this technology to have applications in optics, interior design and art.
