论文摘要
最近有人提出，双曲线超材料中的非凡光波表现出两倍的物理行为（Phys。Rev.Lett。105，067402，2010）。我们通过研究基于铁/钴的铁氟叠质超材料的重力样非线性光学的研究来报告对这种效果的实验观察。除了常规的时间坐标外，沿超材料的光轴定向的空间坐标还表现出及时的特征，这在这些系统中导致了非常不寻常的物理行为。
Recently it was proposed that extraordinary light waves in hyperbolic metamaterials exhibit two times physics behavior (Phys. Rev. Lett. 105, 067402, 2010). We report experimental observation of this effect via investigation of gravity-like nonlinear optics of iron/cobalt-based ferrofluid hyperbolic metamaterials. In addition to conventional temporal coordinate, the spatial coordinate oriented along the optical axis of the metamaterial also exhibits timelike character, which leads to very unusual two times physics behavior in these systems.
