Metasurface超穎透鏡-超穎介面 (又稱超結構metastructure)是一種高工程性的材料, is a highly engineered material that is composed of well controlled nanometer sized elements of different materials so that totally new properties are created. A special class of metamaterials, called metalenses, use high index material structures as small as 30 nm to bend light towards a focal point.
We can make metasurface with high aspect ratio nano-sized patterns for efficient metalenses, working with materials for both visible and IR.
