A Reconfigurable All-Dielectric Metasurface Based on Vanadium Dioxide for Independent Control of the Mie Resonances

All-dielectric metasurfaces have attracted great research interest due to their low loss and versatility to control light. In this paper, we report an active all dielectric metasurface based on Si/VO
₂
hybrid meta-atoms operating in the long wave infrared (LWIR) wavelength range. We show that by judiciously designing the location of VO
₂
layer in the meta-atom, the magnetic dipole resonance can be independently and reconfigurably turned on/off upon phase transition of the VO
₂
material, leaving the electric dipole resonance intact. Our work paves the way for independent control of different Mie resonances in all dielectric metasurfaces for infrared camouflage, radiation control and photodetection applications.
