Reflection and Refraction are key items in terms of understanding our world and how light brightens up everything. Why do straws appear to break in a glass of water? Why does a rainbow exist and how ...

Metasurfaces are two-dimensional (2-D) metamaterials that can control scattering waves of a light beam. Their applications include thin-sheet polarizers, beam splitters, beam steerers and lenses.

Introduction Can you imagine a bouncy ball that could bounce back and forth between two walls, infinitely—that is, forever? Wouldn't that be amazing? What if, instead of a ball, light was bouncing ...

Researchers demonstrate a new technique for suppressing back reflections of light, leading to better signal quality for sensing and information technology. Researchers demonstrate a new technique for ...

Physicists have finally confirmed a phenomenon that sounds like pure science fiction: waves that appear to bounce off a sudden change in time rather than a surface in space. The effect, known as a ...

For more than 50 years, scientists have theorized that a special kind of reflection known as time reflections have existed in the realm of quantum mechanics. However, proving the existence of this ...

There will always be that one topic taught in class that seems unapproachable until it is interpreted differently. For many students, science has always been a subject filled with abstract principles ...
