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.
研究了由铁氧体棒阵列组成的超材料在正入射时的古斯-汉欣（GH）效应。提出了一种新的有效介质方法，并基于变换方法将其应用于获取磁光（MO）超材料的有效参数。对于具有小有效介电常数的结构，预测了在全反射时的巨大正入射古斯-汉欣（NIGH）位移和增强的磁开关效应。进行了数值模拟，结果与变换有效介质方法的结果吻合良好。
