High efficiency near diffraction-limited mid-infrared flat lenses based on metasurface reflectarrays

We report the first mid-infrared flat lens based on the reflectarrays with focusing efficiency (70%), which is the highest reported so far for reflectarray-based lenses. Experiments and simulations show that the focusing is near diffraction-limited.
