Huygens' Metadevices for Parametric Waves

Liu, Mingkai; Powell, David Anthony; Zarate, Yair; Shadrivov, Ilya


Huygens’ metasurfaces demonstrate almost arbitrary control over the shape of a scattered beam; however, its spatial profile is typically fixed at the fabrication time. The dynamic reconfiguration of this beam profile with tunable elements remains challenging, due to the need to maintain the Huygens’ condition across the tuning range. In this work, we experimentally demonstrate that a time-varying metadevice which performs frequency conversion can steer transmitted or reflected beams in an...[Show more]
