For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the ...

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 ...

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 ...

One of the most striking properties of phoxonic metamaterials is their ability to exhibit negative refraction for both light and sound waves. By carefully designing the subwavelength structure of the ...

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 ...
