Chen Shen, assistant professor of mechanical engineering at Rowan University, uses acoustic science to spin and manipulate sound waves for micro applications including miniature robotics and new ...

Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has ...

In context: Sound waves typically propagate in forward and backward directions. This natural movement is problematic in some situations where unwanted reflections cause interference or reduced ...
