Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect ...

WASHINGTON, D.C., August 2, 2016 -- Invisibility cloaks have less to do with magic than with metamaterials. These human-engineered materials have properties that don't occur in nature, allowing them ...

[Asia Economy Reporter Kim Bong-su] Domestic researchers have developed a meta lens capable of simultaneously controlling the three main properties of light?intensity, phase, and polarization. This ...

We investigate the modification of the optical properties of carbon nanotubes (CNTs) resulting from a chemical reaction triggered by the presence of a specific compound (gaseous carbon dioxide (CO 2)) ...
