Why optics needs thickness | Science
Source: science.org
Article summary:
1. Recent developments in fabrication and optical component design have enabled the creation of flat optics or metasurfaces with thicknesses of just several hundred nanometers.
2. This study presents a theoretical approach to determine the minimum thickness required for a specific optical function.
3. The approach is general and can be applied to wave systems such as radio and acoustic systems, as well as optics from cameras to metasurfaces.
