Scientists have developed a new multi-layered metalens design that could revolutionize portable optics in devices like phones, drones, and satellites. By stacking metamaterial layers instead of relying on a single one, the team overcame fundamental limits in focusing multiple wavelengths of light. Their algorithm-driven approach produced intricate nanostructures shaped like clovers, propellers, and squares, enabling improved performance, scalability, and polarization independence.
