Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.

Metamaterials researchers at Duke University have demonstrated the design and construction of a thin material that can control the redirection and reflection of sound waves with almost perfect ...

Scientists have hypothesized for over six decades the possibility of observing a form of wave reflections known as temporal, or time, reflections. Researchers detail a breakthrough experiment in which ...
