Dispersion is an inherent property of optical elements, and can be controlled via different kinds of optical glasses or binary optics conventionally. In this paper, we show that this property can be manipulated by the dielectric metasurfaces. In addition, we design the metalenses and beam deflectors with positive, zero, and negative dispersion in the mid-infrared. Unit cells of different sizes and different rotation angles have been introduced to facilitate simultaneous manipulation of phase and its dispersion characteristics. Simulation results show that, the designed metasurfaces demonstrate desired chromatic dispersion. This work paves the way to the practical application of metasurfaces.
