Tailor-made light passes through opaque obstacles like they’re not there

A simulated image of the experimental setup, where light waves can be manipulated so they project the image of the Big Dipper through the opaque scattering medium (zinc oxide) as though the barrier isn't there

Even diffuse objects like clouds or sugar cubes cast shadows, because they’re disordered media that scatter light waves. But now, researchers at TU Wien and Utrecht University have found a way to manipulate light waves to pass through, projecting an image on the other side as clearly as if the obstacle wasn’t there.
