Holograms are three-dimensional (3D) images produced by interfering beams of light that reflect physical objects or photographs. In recent years, they were introduced in a variety of settings, for instance to enhance employee ...
Metamaterials, made up of small, repeated structures, engineered to produce desired interactions with light or sound waves, can improve optical devices used in telecommunications, imaging and more. But the functionality of ...
