Abstract

Goos-Hänchen (GH) effects at normal incidence are investigated for metamaterials consisting of an array of ferrite rods. A new effective-medium approach is presented and applied to retrieve the effective parameters of the magneto-optical (MO) metamaterials based on a transformation method. Giant normal-incidence Goos-Hänchen (NIGH) shifts on total reflection and enhanced magnetic switching effects are predicted near magnetic surface plasmon (MSP) resonances for structures with small effective permittivity. Numerical simulations are performed and the results are in good agreement with those from the transformation effective-medium approach.
