The ability of double-negative metamaterials to possess unusual electromagnetic responses is bestowed by the special resonances provided by its unit structure. This principle is equally valid for ...

This is claimed to be the shortest wavelength yet for such a metamaterial and lies just outside of the visible spectrum at 380-780 nm. The previous record had been about 1500 nm, and the result is an ...

However, these metamaterials are constructed in fixed geometries, meaning their unique abilities are always fixed. Now, new 3-D printed metamaterial can be remotely switched between active control ...

The result is a metamaterial, pictured at the top of this page, that is capable of achieving a negative index of refraction at wavelengths as small as 1500 nanometers.

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 ...
