Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

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

Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic ...

Recent studies have demonstrated engineering metamaterials with unprecedented characteristics such as left-handedness with simultaneous negative permittivity and permeability, negative lens that focus ...

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 ...

The field of metamaterials is an emerging discipline in the early 21st century, attracting significant attention in fundamental science and engineering applications. Recently, a comprehensive review ...
