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 ...

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 ...

Optics researchers have long been fascinated by the properties of metamaterials, such as the predicted 'superlensing' — subdiffraction focusing — from negative-refractive-index materials.

By arranging the nanoscale unit cells in a desired geometry, the refractive index of the metamaterial can be adjusted to positive, near-zero, or negative values. Among the most sought-after properties ...

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 ...
