Electromagnetic waves in uniaxial crystals: General formalism with an application to Bessel beams

摘要

We present a mathematical formalism describing the propagation of acompletely general electromagnetic wave in a birefringent medium. Analyticformulas for the refraction and reflection from a plane interface are obtained.As a particular example, a Bessel beam impinging at an arbitrary angle isanalyzed in detail. Some numerical results showing the formation anddestruction of optical vortices are presented.
