The negative refraction of electrons in graphene has been seen for the first time in experiments done by physicists in the US. The work represents an important advance in the fabrication of graphene ...

Physicists in Germany claim to have found the first naturally occurring material that has a negative, rather than a positive, refractive index. The material -- a metallic ferromagnet -- is very ...

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 ...

What color is the coronavirus? Conventional optical microscopes are unable to generate high-resolution, colored images of viruses and bacteria. Expensive equipment is used to view them in a more real ...

Physicists are involved in an unusually heated debate over the reality of a new kind of refraction and about the possibility of making perfect lenses. Edwin Cartlidge reports. If you think science is ...

WEST LAFAYETTE, Ind. – Engineers at Purdue University are the first researchers to create a material that has a "negative index of refraction" in the wavelength of light used for telecommunications, a ...

Nearly a decade after getting waves of light to bend backward, physicists have done the same with electrons. Electrons coursing through a sheet of carbon atoms exhibited negative refraction, bending ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

There has been interest in the Negative Refraction Index (NRI) material at optical frequencies. There are two approaches to optical frequencies. 1)Volumetric structure: it is based on the spherical ...
