Abstract

We study nonspecular phenomena experienced by two-dimensional ordinary and extraordinary beams propagating in a uniaxial crystal and reflected at a flat uniaxial–isotropic interface. We extend to uniaxial crystals the aberrationless approach used for beams in isotropic media. Analytical expressions for the geometrical nonspecular effects (lateral shift, focal shift, angular shift, and beam waist modification) are given and compared with those predicted by the stationary phase approximation. The theory is applied to the reflection of beams at a flat interface between ${\mathrm{TiO}}_2$ and a vacuum.
