我们研究了纳米线超材料附近(或内)的切伦科夫辐射，证明了由于这种结构中的电磁态密度异常高，与自然介质相比，切伦科夫辐射有可能提高几个数量级，并产生没有带电粒子速度阈值的切伦科夫辐射。
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.
