Researchers developed a numerical simulation technique for light wave interactions in triangular-lattice PCSELs, enhancing performance and design scalability.
For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the ...
Elad Harel is used to shining a light on the mysteries of the natural world. Working at the cutting-edge of ultrafast ...
Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic arrays instead of engineered metamaterials. This breakthrough has enormous ...
Einstein predicted the existence of gravitationally-warped rings of light in 1915. Now, a new one has been discovered just a ...
