For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

An unexpected discovery in a Harvard lab has led to a breakthrough insight into choosing an unconventional material, silica, ...

Capasso himelf called the discovery “a counterintuitive breakthrough in nanotechnology.” He added, “We have demonstrated in ...

Harvard researchers have found that silica, long thought to lack the right properties for optical metasurfaces, can sometimes ...

Well, OK, not exactly. A beam of light could pass through air all day long (as long as you have a layer of air 26 billion kilometers long) and not deviate a whit. But if the density of that air ...

A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

Lake Oswego, OR - January 08, 2026 - PRESSADVANTAGE - At Tersigni Vision, a growing number of patients are asking ...

Researchers report the development of ultrahigh refractive index metamaterials which are integrated with a low refractive index polymer producing distributed Bragg reflector (DBR). The highest ...
