A true cloak of invisibility, as seen in the Harry Potter series, may soon come to fruition as scientists discover ways to ‘bend’ light around objects.
The team of electrical engineers from Duke University, who created the first ‘cloaking’ device in 2006, have been working on ways to iron out the problems of the earlier cloak (check out our previous article right here). Previous distortions meant that when look at the device people were aware of its presence, much the same way you are aware of the glass when looking out of a window.
Now the team believe they have created ‘true’ invisibility by using materials that are capable of bending electromagnetic waves, such as light, around the object. This means that when looking at the current version of the cloak, a ‘diamond-shaped fibreglass and copper sheet’, people will only be able to see the light behind the concealed object, effectively making it invisible.
The Duke University scientists are now researching ways in which they can apply these principles to a three dimensional device.
What do you think of this new research? What other magical Potter object would you like to be made a reality?
