传统的基于欧几里得变换光学的隐身要求隐身衣内表面的光速趋于无穷大。非欧几里德隐形仍然需要具有超光速传播的介质。在这里，我们通过举例说明这不再是必要的。
Conventional cloaking based on Euclidean transformation optics requires that the speed of light should tend to infinity on the inner surface of the cloak. Non-Euclidean cloaking still needs media with superluminal propagation. Here we show by giving an example that this is no longer necessary.
