The metamaterial has an angle-independent negative refractive index, enabling it to act as a flat lens. When illuminated with UV light (purple) a sample object of any shape placed on the flat slab of ...

A metamaterial is an artificially engineered material made from an array of unit cells that are carefully designed to produce a desirable electromagnetic response. A common design of unit cell is ...

Their paper, entitled A first-in-human pilot study of a novel electrically-passive metamaterial-inspired resonator-based ocular sensor embedded contact lens monitoring intraocular pressure ...
