Vanadium dioxide (VO₂) can achieve dynamic modulation across an ultra-wide bandwidth from visible to microwaves. Firstly, by constructing double-sided nanoparticle VO₂ films, the surface plasmon resonance effect in the near-infrared band are utilized to simultaneously enhance visible transmittance and thermal modulation ability. Secondly, by combining the Fabry-Perot resonance effect, significant regulation of infrared emissivity is achieved by VO₂ device. Finally, based on the change in conductivity, VO₂ based composite materials are constructed to realize large-amplitude dynamic electromagnetic modulation over a wide bandwidth.
