Abstract
In this work, a numerical analysis of multilayered thermochromic surfaces composed of dielectrics and the transition metal oxide VO2 was carried out using the finite element method. The transmittance of the multilayered device has been analyzed by changing the incident angle and geometric parameters. It has been demonstrated that the optical properties of the analyzed structure changes with the temperature achieving a satisfactory performance and the solar light modulation occurs at the near infrared wavelength region of the solar spectrum. In this way they become suitable for smart windows applications.
