When will the protruding rear camera on smartphones become obsolete? The implementation of a metasurface, which completely disregards the properties of light, promises to reduce the thickness of a camera lens to 1/10,000 of a conventional lens. However, despite this advancement, challenges still persist due to high production costs and intricate processes. A recent study unveiled a “mold” that dissolves in water, enhancing the efficiency of the fabrication process.
