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 ...
The work was published in Science ("Gate-tunable negative refraction of mid-infrared polaritons"). Basic principle of the “polariton transistor”. The van der Waals heterostructure is constructed by ...
What color is the coronavirus? Conventional optical microscopes are unable to generate high-resolution, colored images of viruses and bacteria. Expensive equipment is used to view them in a more real ...
