磁性光子晶体的“整流”反射
"Rectifying" reflection from a magnetic photonic crystal
摘要：
当一个振荡的线源被放置在一个特殊的镜子前面，镜子由一个均匀间隔的扁平铁氧体棒阵列组成，在某个频率下，一半的图像消失了。我们认为这是由于磁表面等离子体激元带与光子态的耦合。由于时间反演对称性破缺，这些态呈现出只向一个方向运动的巨大环流。这种“整流”反射的可能应用包括一个鲁棒的单向波导，一个90度的光束弯曲器和一个分束器，它们甚至可以在深亚波长范围内工作。
英文摘要：
When an oscillating line source is placed in front of a special mirror consisting of an array of flat uniformly spaced ferrite rods, half of the image disappeared at some frequency. We believe that this comes from the coupling to photonic states of the magnetic surface plasmon band. These states exhibit giant circulations that only go in one direction due to time reversal symmetry breaking. Possible applications of this "rectifying" reflection include a robust one-way waveguide, a 90 degree beam bender and a beam splitter, which are shown to work even in the deep subwavelength scale.
