Abstract :
Achromatic metasurfaces are introduced for multiwavelength light control. An engineered wavelength-dependent phase response preserves the functionality within a certain bandwidth. Scattering properties of dielectric resonators are explored to demonstrate a dispersion-free beam deflector and an achromatic lens.
