We rigorously derive the formulas of the total electric and magnetic fields in a slab of anisotropic negative refractive medium by use of Maxwell’s equations. A beam shifting is exhibited from a Gaussian beam for an anisotropic negative refractive slab. Our results indicate that there exist two possible (positive or negative) beam shifting for an anisotropic negative refractive medium due to the special anisotropic properties, which is distinct from the case of an isotropic negative refractive slab. Physical insights are also presented.
