Sketch of the concept: a disordered medium (top) is made perfectly transmitting by placing a custom-made anti-reflection coating in front of it (bottom). (Courtesy: TU Wien) A new technique that ...

Owing to the wave nature of light there are many ways that such different waves can interact with each other, but also with materials. Everyone knows about reflecting light with a mirror, which is a ...

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

As showing how far under favourable conditions the reflection of light from a cloudy sky is visible, I may perhaps be allowed to mention that last night at nine o'clock the reflection of the London ...

Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...
