我们用超材料实验实现了横波的布鲁斯特效应。在介电介质中，布鲁斯特无反射效应仅对横磁波产生。然而，理论上已经预测了在相对磁导率mu(r)不等于单位的情况下，TE波会产生布鲁斯特效应。我们用时域有限差分法设计了一组分裂环谐振器作为mu(r)不等于1的超材料。在3ghz波段进行了反射测量，证实了在特定入射角下反射波的消失。
We have experimentally realized Brewster's effect for transverse-electric waves with metamaterials. In dielectric media, Brewster's no-reflection effect arises only for transverse-magnetic waves. However, it has been theoretically predicted that Brewster's effect arises for TE waves under the condition that the relative permeability mu(r) is not equal to unity. We have designed an array of split-ring resonators as a metamaterial with mu(r)not equal 1 using a finite-difference time-domain method. The reflection measurements were carried out in a 3-GHz region and the disappearance of reflected waves at a particular incident angle was confirmed.
