Metamaterial Made of Paper and Aluminum Manipulates Acoustic Waves

Caption

The metamaterial, shown here, is made of paper and aluminum -- but its structure allows it to manipulate acoustic waves to more than double the resolution of acoustic imaging, focus acoustic waves, and control the angles at which sound passes through the metamaterial. Acoustic imaging tools are used in both medical diagnostics and in testing the structural integrity of everything from airplanes to bridges.
