We characterize both the ordinary and extraordinary refractive indexes of columnar thin films (CTFs) as Gaussian functions of the vapor incidence angle. This simple model is compared to the one available in literature for three different materials, resulting in low relative errors. The Gaussian model can be easily used to design Bragg multilayers made of CTFs.
