    "abstract": "The propagation of a Bessel beam (or Bessel-X wave) is analyzed on the basis\nof a vectorial treatment. The electric and magnetic fields are obtained by\nconsidering a realistic situation able to generate that kind of scalar field.\nSpecifically, we analyze the field due to a ring-shaped aperture over a\nmetallic screen on which a linearly polarized plane wave impinges. On this\nbasis, and in the far field approximation, we can obtain information about the\npropagation of energy flux and the velocity of the energy.",
