This work shows that the existence of a Brewster angle in interfaces between the vacuum and an uniaxial crystal may be explained by means of the dipolar model. This is achieved by the introduction of the electric polarization vector instead of the electric field. It is shown that a polarization of the incident ray exists, for which the vectors P′ (electric polarization vector of the ordinary wave) and P″ (electric polarization vector of the extraordinary wave) are so that the components perpendicular to the incidence plane are equal and opposite. The resulting P vector in this case is in the incidence plane and has the direction of the reflected ray when the incidence angle is that of Brewster.
