Shape Optimization for High Efficiency Metasurfaces: Theory and Implementation
Chinese Academy of Sciences

Metasurfaces are formed by engineering a glass surface with an array of microscopic features, or meta-atoms. Although different optical functionalities can be obtained by changing only the pattern, the resulting metasurfaces often lack the necessary efficiency for many applications. In this report, scientists from Corning and Harvard University collaborate to demonstrate an inverse-design method that optimizes efficiency while respecting fabrication constraints. These results represent a step forward in making practical metasurfaces for broader applications.
