Tunable Mie-Resonant Dielectric Metasurfaces Based on VO 2 Phase-Change Materials
2020
We demonstrate Mie-resonant silicon metasurfaces tunable via the insulator-to-metal transition of a deposited VO 2 layer. We observe two orders of magnitude modulation depth of the metasurface reflection with reversible properties and a hysteresis-like behavior.
