Propagation of Gaussian beam through a uniaxial anisotropic slab

• Gaussian beam is expanded in terms of the rectangular vector wave functions.
• Propagation of Gaussian beam through a uniaxial anisotropic slab is studied.
• Normalized field intensity distributions are provided.

An exact analytical solution to the reflection and transmission of an incident Gaussian beam by a uniaxial anisotropic slab is obtained in terms of the rectangular vector wave function expansion form. In the uniaxial anisotropic slab, the optical axis is parallel to the interface. For a localized beam model, numerical results of the normalized field intensity distributions are presented, and the propagation characteristics are analyzed concisely.
