Figure 2

Dual Functional Metalenses paradigm for vector beams generation: using an impinging circularly polarized light (a,b), it is possible to generate focalized OAM beams with flipped helicity and opposite spin. Thus, for impinging linearly polarized light (c,d), it is possible to generate vector beams, such as the azimuthally polarized vector beam (Az-VB, c) or the radially polarized vector beam (Rad-VB, d).
