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 ...

Stabilization issue of anomalous refraction and reflection in V-shaped antenna metasurfaces are investigated. Specifically, when a V-shaped metasurface is artificially tilted, the induced refraction ...

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 ...
