When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even exist? Recently, researchers at Nanjing University in China created a material from polyethylene membranes that does exactly that.
