Bessel Beam through a Slab at Oblique Incidence: The Case of Oblique Incidence

The oblique incidence of a Bessel beam into a plane-parallel layer of a medium with refractive index m surrounded by a medium of a refractive index n>m may be studied simply by expanding the Bessel beam into a set of plane waves forming the same angle with the axis of the beam. In the present paper we examine a Bessel beam that impinges at oblique incidence onto a layer in such a way that each plane-wave component impinges with an angle larger than the limit angle.
