Switchable metasurface with vo2 thin film at visible light by changing temperature

HIGHLIGHTS

  • who: Jin-Kyu Yang and Hyeon-Seok Jeong from the Department of Optical Engineering, Kongju National University, Cheonan, Korea have published the paper: Switchable Metasurface with VO2 Thin Film at Visible Light by Changing Temperature, in the Journal: Photonics 2021, 8, 57. of /2021/
  • what: We numerically demonstrated switchable metasurfaces using a thin-VO2 -film based reflectarray of Au nanorods in the visible region at λ=700 nm.
  • how: The authors used the classical dispersion model based on the Drude-Lorentz model to realize the optical constant of a thin VO2 film in both . . .
