Vanadium dioxide (VO₂) shows an abrupt change in optical and electrical properties when its temperature is raised beyond a critical point of ~68ºC. Films made from such materials have a potential to be used in smart windows with dynamic throughput of solar radiation. Two of the drawbacks of this material have been its low luminous transmittance and small solar transmittance modulation during switching. In this work we report  calculations and experiments on multilayers of VO₂ and TiO₂ films produced by reactive magnetron sputtering, that significantly improve the luminous transmittance and solar modulation of the films during switching.
