Analysis of the focal spot by variation of immersion medium for nanostructured metasurfaces
The refractive index of the immersion medium has a significant influence on the shape of the focal spot in the field of diffraction optics. For a refractive index of the immersion medium that varies from the designed one, the change in the focal properties of the diffractive optical elements needs t...
