3-D printed active metamaterials for sound and vibration control

3-D printed active metamaterials for sound and vibration control 04/17/2018 12:50 PM EDT Researchers have been pushing the capabilities of materials by carefully designing precise structures that exhibit abnormal properties that can control acoustic or optical waves. However, these metamaterials are constructed in fixed geometries, meaning their unique abilities are always fixed. Now, new 3-D printed metamaterial developed by a team led by University of Southern California researchers can be remotely switched between active control and passive states.
