Field	Optics, masers and lasers
Keywords	invisible cloaking; transformation optics; subluminal propagation
Description	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.
