双曲超材料界面：来自Rindler视界的霍金辐射和“时间的终结”
Hyperbolic metamaterial interfaces: Hawking radiation from Rindler horizons and the "end of time"
摘要：
双曲型超材料中的非寻常射线表现为三维（2+1）闵可夫斯基时空中的粒子世界线。我们分析电磁场的行为在这个有效的时空的边界取决于边界方向。如果边界垂直于超材料中的类空方向，则可以观察到产生霍金辐射的有效林德勒视界。另一方面，如果边界垂直于类时方向，则会产生一种不寻常的物理情况，可以称为“时间的终结”。看来，在无损近似电磁场发散的界面处，在这两种情况下。使用等离子体超材料对“时间终结”的实验观察证实了这一结论。
英文摘要：
Extraordinary rays in a hyperbolic metamaterial behave as particle world lines in a three dimensional (2+1) Minkowski spacetime. We analyze electromagnetic field behavior at the boundaries of this effective spacetime depending on the boundary orientation. If the boundary is perpendicular to the space-like direction in the metamaterial, an effective Rindler horizon may be observed which produces Hawking radiation. On the other hand, if the boundary is perpendicular to the time-like direction an unusual physics situation is created, which can be called "the end of time". It appears that in the lossless approximation electromagnetic field diverges at the interface in both situations. Experimental observations of the "end of time" using plasmonic metamaterials confirm this conclusion.
