​We investigate the behavior of full-vector electromagnetic Bessel beams obliquely incident at an interface between two electrically different media. We employ a Fourier transform domain representation of Bessel beams to determine their behavior upon reflection and transmission. This transform, which is geometric in nature, consists of an elliptical support curves with complex weighting associated with them. The behavior of the scattered field at an interface is highly complex owing to its full-vector nature; nevertheless this behavior has a straightforward representation in the transform domain geometry. The analysis shows that the reflected field form a different vector Bessel beam, but in general, the transmitted field cannot be represented as a Bessel beam. Nevertheless, using this approach, we demonstrate a method to propagate a Bessel beam in the refractive medium by launching a non-Bessel beam at the interface. Several interesting phenomena related to the behavior of Bessel beams are illustrated, such as polarized reflection at Brewster’s angle incidence, and the Goos-Hänchen and Imbert-Federov shifts in the case of total reflection.
