Sound can do more than just provide a nice beat. Sound waves have been used for everything from mapping the seafloor to ...

Dajun Zhang, a doctoral student at the University of Wisconsin-Madison, has developed a new metamaterial that lets scientists ...

Acoustic metamaterials could be used in many applications. Large versions could be used to direct or focus sound to a particular location and form an audio hotspot. Much smaller versions could be used ...

The established framework shows potential for extension to other spectral ranges (THz/optical frequencies) and multidisciplinary applications (e.g., acoustic metamaterials), significantly ...

OMAMs, multifunctional tunable ultradeep subwavelength metamaterials, enable the generation of multiple arbitrary acoustic fields with ultradeep subwavelength resolution, facilitate the switching ...

Metamaterials that mimic the order in matters have opened an exciting gateway to reach unprecedented physical properties and functionality unattainable from naturally existing materials. The "atoms" ...

Engineers have fabricated a metamaterial that is not only strong but also stretchy. Their new method could enable stretchable ceramics, glass, and metals, for tear-proof textiles or stretchy ...

Overall behavior of composite materials and metamaterials. The fundamentals of homogenization for elastic composites, variational principles and energy-based bounds, and dynamic homogenization ...
