We analyze electromagnetic field propagation through a random medium that consists of hyperbolic metamaterial domains separated by regions of normal "elliptic" space. This situation may occur in a problem as common as 9 μm light propagation through a pile of sand, or as exotic as electromagnetic field behavior in the early universe immediately after the electroweak phase transition. We demonstrate that spatial field distributions in random hyperbolic and random "elliptic" media look strikingly different. Optical field is strongly enhanced at the boundaries of hyperbolic domains. This effect may potentially be used to evaluate the magnitude of magnetic fields which existed in the early universe.
我们分析了通过由双曲超材料域和正常“椭圆”空间区域组成的随机介质的电磁场传播。这种情况可能出现在像 9 μm 光通过一堆沙子这样常见的问题中，或者像早期宇宙中电弱相变后电磁场行为那样具有奇特性质的问题中。我们证明了随机双曲和随机“椭圆”介质中的空间场分布有显著的不同。在双曲域的边界处光学场得到了强烈增强。这种效应可能会被用来评估早期宇宙中存在的磁场的大小。
