Rendering things invisible sounds like it belongs in the realm of Harry Potter, but it is technically possible. Researchers from TU Wien in Austria have developed a new process that allows light waves to pass right through a material by projecting a matching Wave pattern onto it, actively camouflaging the target from view. The technique could one day be used as a kind of invisibility cloak, and it might work just as well on sound waves.
