More than 80 bronze mirrors made during the Western Han Dynasty were discovered in a large-scale ancient tomb in China. Although some 2,000 year old, many of the mirrors are still reflective and show ...

Figure 1: Optical properties of a metamaterial mirror. The critical importance of the groove dimensions in the overall design of the magnetic mirror can be understood in more depth by realizing that ...

Researchers show that switching between reflective and scattering states can be achieved with just 1.4 V, about the same voltage used to light a typical LED. Researchers have developed a way to ...

R¿diger Paschotta, a physicist and CEO of RP Photonics Consulting in Switzerland, offers this answer. There are many different types of mirrors, and each behaves somewhat differently. The most common ...

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 ...
