When we talk of an invisibility cloak, Harry Potter series comes rushing to our thoughts. That said, the concept of cloaking isn’t restricted to movies alone, we’ve seen them being tested in real, and its success can be figured from this, that now Scientists from Karlsruhe Institute of Technology in Germany have created an invisibility cloak in 3D.
This besides anything is perhaps the first attempt of render objects invisible in three-dimension. Here the researcher used ‘photonic crystals with a structure resembling piles of wood in order to render a small bump on a gold surface invisible in 3D.’ The cloak used for disappearing the bump, is made in special lenses that distort the light hitting the object this concealing the bump. Reasearchers will now be working on increasing the size of the concealed object, which we guess would also be a successful venture. Let’s wait to see some positives coming from there.
