WebHere, the complex refractive index of VO2 thin films across the IMT is characterized for free‐space wavelengths from 300 nm to 30 µm, using broadband spectroscopic ellipsometry, reflection spectroscopy, and the application of effective‐medium theory. VO2 films of different thicknesses are studied, on two different substrates (silicon and ... WebIn related art, vanadium dioxide (VO2), which is one of the phase change materials for metal antennas, is used as a phase change material. In this case, a current is applied to a gold (Au) antenna to change the phase of VO2, and the phase is modulated is this manner. ... the refractive index of the material included in the grating 210 may be ...
