Parallel beams and fans of rays in uniaxial crystals
In this work, we show how different kinds of plane beams are refracted when they are transmitted through an uniaxial parallel plate immersed in an isotropic medium. When the incident manifold of rays is a beam of parallel rays, two parallel beams are transmitted through the plate. Nevertheless, they...

| Sumario: | In this work, we show how different kinds of plane beams are refracted when they are transmitted through an uniaxial parallel plate immersed in an isotropic medium. When the incident manifold of rays is a beam of parallel rays, two parallel beams are transmitted through the plate. Nevertheless, they are not overlapped. If the incident beam is a fan of rays such that its vertex lies on the first interface, the extraordinary rays will be contained in a plane surface (termed "extraordinary refraction plane") but the surface that contains the transmitted beam through the plate becomes warped. If the vertex is not on the first interface, the extraordinary refracted beam won't be plane neither in the crystal nor in the isotropic medium. The behavior of transmitted beams that corresponds to ordinary rays is analogous to that of beams transmitted through isotropic plates. © 2008 American Institute of Physics. |
