In this contribution, we discuss the possibility of exploiting the theory of composite vortices for manipulating the reflected beam by a single reflective metasurface. In particular, by designing a metasurface able to reflect both a vortex and a vortex-free component, we show that its scattering pattern can be tilted according to the amplitude ratio between the two components. This preliminary results confirm that composite vortex properties can be exploited for beam-shaping applications in different frequency ranges.

Abstract
In this contribution, we discuss the possibility of exploiting the theory of composite vortices for manipulating the reflected beam by a single reflective metasurface. In particular, by designing a metasurface able to reflect both a vortex and a vortex-free component, we show that its scattering pattern can be tilted according to the amplitude ratio between the two components. This preliminary results confirm that composite vortex properties can be exploited for beam-shaping applications in different frequency ranges.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
