Book review: ‘Invisibility’ by Gregory J Gbur
Apr 12, 2023 · After millennia of storytelling about invisibility, 2006 saw the appearance of two papers which described how an object might be hidden by guiding light around it. In principle, this could render an object invisible.
How Many Ways Can We Make Something Invisible?
Apr 11, 2023 · Invisibility—the ability to make something invisible to visible light—has long been assumed by science to be impossible. This changed in 2006, when two groups of researchers published back-to-back papers in the …

Invisibility: The History and Science of How Not to Be Seen
See more on nextbigideaclub.comIt was long thought by physicists that perfect invisibility is impossible, but in 2006 two groups of researchers, one at the University of St. Andrews and the other a collaboration between Imperial College and Duke University, demonstrated theoretically that it is possible to make an optical invisibility cloak. These origina…Exploring the ingenious science and science fiction of …
Jul 17, 2023 · When light passes through the material, it bends around the cloaked object, rendering it "invisible." You can see an object directly behind it but can't see the cloaked object itself.
3D Visible‐Light Invisibility Cloak - PMC
Here, we achieve a 3D cloak for visible light by performing a 3D polyhedral transformation and using an approach involving a spatially invariant refractive index discretization. Our …
