We suggest a novel type of photonic topological edge states in zigzag arrays of dielectric nanoparticles based on optically induced magnetic Mie resonances. We verify our general concept by the proof-of-principle microwave experiments with dielectric spherical particles, and demonstrate, experimentally, the ability to control the subwavelength topologically protected electromagnetic edge modes by changing the polarization of the incident wave.
我们基于光学诱导的磁米氏共振，提出了一种新型的介电纳米颗粒锯齿阵列中的光子拓扑边缘态。我们通过使用介电球形颗粒的原理验证微波实验来验证我们的一般概念，并通过实验证明了通过改变入射波的极化来控制亚波长拓扑保护电磁边缘模式的能力。
