Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3D displays, virtual reality and even self-driving vehicles. Microscopic crystals in tantalum disulfide ...

What makes it distinct from other metamaterials is that it is made entirely from semiconductor material — the stuff found in computer chips and prized for its ability to act as ...

From superlenses that break the diffraction limit to cloaking devices once only imagined in sci-fi, breakthroughs in light-bending materials are redefining optics. At the heart of this revolution is ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

The Brix scale, derived from the refractive index of a solution at 20 degrees Celsius (68 Fahrenheit), is widely known. Originally, it was established by determining the weight percentage of sucrose ...
