PITTSBURGH (KDKA) - The universe is full of waves, and they are not all created equally. Some are mechanical, and others are electromagnetic, even though they are all energy! Not all waves are created ...

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 ...

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 ...

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 ...

Ocean waves have long been seen as having huge potential as a source of renewable energy. Waves produce an estimated 50 trillion to 80 trillion watts of power worldwide – nearly two to three times the ...
