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 ...

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 ...

High-surface-area materials such as porous carbon, polymers and metal–organic frameworks have high hydrogen storage capabilities at cryogenic temperature. The small hydrogen adsorption ...

Researchers find negative-time light, which could allow for time travel. An intriguing phenomenon in quantum mechanics made ...

The creation of a negative refractive index — responsible for a host of interesting phenomena, including negative refraction, the inverse Doppler effect and reverse Čerenkov radiation ...

We will cover the following areas: (a) Near Field Imaging: Field propagation, Diffraction limit, Near field scanning optical microscope (NSOM); (b) Meta-Material and Plasmon Based Devices: Negative ...

Specific topics include sub-wavelength waveguiding and focusing, super-resolution imaging and nano-lithography beyond the diffraction limit of the light, negative refraction, and invisibility cloaking ...
