You don’t have to be a Harry Potter nerd to dream of having one of these babies! We all wanted one when we saw the movies, but now studies say they’re a little less magical and a little more scientific than you think.
According to Mirror this is how the “invisibility” effect works…
Scientists have long believed the key to an invisibility cloak, as featured in Harry Potter , is the manipulation of light. The fundamentally new approach overcomes critical shortcomings of previous attempts.
It offers hope of securing data transmitted over fibre optic lines, thwarting eavesdroppers, and improving technologies for sensing, telecommunications and information processing.
The concept, theoretically, could also be extended to make 3D objects invisible from all directions, said the researchers.
The spectral cloak operates by selectively transferring energy between certain colours of the light wave.
After the wave has passed through the object, the device restores the light to its original state.
When viewing an object, what you are really seeing is the way in which it modifies the energy of the light waves that interact with it.
I suck at science, so if you want to read more about the study, read more about it from Mirror HERE.
