Abstract
Both positive and negative lateral shifts are demonstrated in this paper for a Gaussian beam reflected from an anisotropic grounded slab, whose constructive parameters are determined by the optical transformation approach. The incident wave is modeled as a tapered wave with a spatial Gaussian shape. Layered structures with alternating isotropic materials are applied to model the parameters of such an anisotropic grounded slab and good agreements are obtained when the positive lateral shifts caused by ideal anisotropic slab are compared with those of the equivalent isotropic layered slab.
