Abstract The properties of optimized transverse magneto-optical Kerr effect (TMOKE) of all-types of bi-gyrotropic metamaterials have been investigated and compared for both s- and p-polarized waves. We demonstrated that double-positive and double-negative ones are capable of achieving maximum TMOKEs, but with the opposite signs. On the other hand, single-negative metamaterials could not provide large TMOKE. In addition, a giant TMOKE can be observed in a special case of metamaterials whose are exhibiting near-zero refractive index. A large TMOKE response is important for applications in magneto-optical data storage and high-definition imaging.

双正、双负和单负双回旋超材料中横向磁光克尔效应的性能

摘要 研究和比较了所有类型的双回旋超材料的优化横向磁光克尔效应 (TMOKE) 的特性，并针对 s 和 p 极化波进行了比较。我们证明了双正和双负能够实现最大的 TMOKE，但符号相反。另一方面，单负极超材料无法提供大的 TMOKE。此外，在超材料的特殊情况下可以观察到巨大的 TMOKE，其折射率接近于零。大 TMOKE 响应对于磁光数据存储和高清成像中的应用很重要。
