In this paper, we design and simulate a single and a bifocal lens at the wavelength of 700 nm. Metasurfaces are 2-D form of bulky metamaterials which consist of an array of resonators. To reduce the radiative loss and enhancement of efficiency, we take advantage of dielectric resonators such as Silicon. In these constitutions, the resonance modes excited by means of displacement currents. Finally, to focus the incident light at two different areas, a phase modulation has been applied on the arrangement of resonators.
