First Acoustic Metamaterial Device reconfigurable in Real Time

Dynamically altering the form of a three-dimensional colloidal crystal in real time is possible, research from the University of Bristol’s Department of Mechanical Engineering shows. This was done using an acoustic metadevice that is able to influence the acoustic space and control any of the ways in which sound waves travel. The colloidal crystals in the study, called metamaterials, are artificially designed and structured materials which expand the properties of existing natural materials and compounds. [Read More]
