Abstract

It is found that the generalized Goos–Hänchen (GGH) shift of a light beam reflecting from a double negative metamaterial slab backed by a metal can be large positive as well as negative. We give an analytical expression for the GGH shift from which the necessary condition for the GGH shift to be positive or negative can be obtained. Numerical results validate the conclusions. A Gaussian-shaped beam was analyzed in the paraxial approximation and it was proven that there is no angular shift in this case. Finally we discuss the lossy effect of the metamaterial slab on the GGH shift.
