We study the Cherenkov emission in the vicinity of (or within) a nanowire metamaterial, and demonstrate that due to the anomalously high density of electromagnetic states in such structures, it is possible to boost the Cherenkov emission by several orders of magnitude as compared to natural media, and produce Cherenkov radiation with no threshold for the velocity of the charged particles.
