A multipeak Metasurfaces are the two dimensional equivalents of bulk metamaterials [1, 2], which represent a
sudden variation of optical properties when an incident wave interacts with it, yielding the most exotic optical
phenomena, such as broadband absorption, wavefront shaping or the anomalous refraction and reflection. This paper
proposes, through simulations, a model of a purely dielectric metasurface without losses, allowing the incident
wave’s global phase control, from - π to π, for operation on optical frequencies (1.55 μm) by inserting structures that
have contrasting refractive indexes. To demonstrate the phase control, a linear phase profile has been utilized to
cause the anomalous refraction phenomena, which has applications in wireless optical communications.
