We study the electromagnetic beam reflection from layered structures that include the so-called double-negative metamaterials, also called left-handed metamaterials. We predict that such structures can demonstrate a giant lateral Goos-Hänchen shift of the scattered beam accompanied by a splitting of the reflected and transmitted beams due to the resonant excitation of surface waves at the interfaces between the conventional and double-negative materials as well as due to the excitation of leaky modes in the layered structures. The beam shift can be either positive or negative, depending on the type of the guided waves excited by the incoming beam. We also perform finite-difference time-domain simulations and confirm the major effects predicted analytically.
我们研究了来自包含所谓双负超材料（也称为左手超材料）的分层结构的电磁束反射。我们预测，由于传统材料与双负材料界面处表面波的共振激发以及分层结构中泄漏模式的激发，此类结构可表现出散射光束的巨大横向古斯-汉欣位移，并伴有反射光束和透射光束的分裂。光束位移可以是正的或负的，这取决于入射光束激发的导波类型。我们还进行了时域有限差分模拟，并证实了分析预测的主要效应。
