A team of researchers with members from Wuhan University and the University of Texas has created an artificial material that offers both negative refraction and no reflection. In their paper published ...
In 1621, Dutch astronomer Willebrord Snell mathematically described how a light wave behaves when it crosses a boundary between media with different refractive indices. Since then, Snell’s law of ...
At the interface between two facets of an artificial crystal, sound waves can be transmitted in the opposite direction to that expected, and undergo no reflection. Such wave behaviour could have many ...
