A joint research team from Korea’s Pohang University of Science and Technology (POSTECH) and Northeastern University (NEU) in the US have succeeded in transporting light using non-Hermitian meta-gratings.
Light is a very delicate and vulnerable property. Light can be absorbed or reflected at the surface of a material depending on the matter’s properties or change its form and be converted into thermal energy. Upon reaching a metallic material’s surface, light also tends to lose energy to the electrons inside the metal, a broad range of phenomena we call “optical loss.”
Production of…
