摘要：

We introduce a method to realize superluminal phase velocity of electromagnetic wave which can be five thousand times larger than c (c is the speed of light in vacuum) in dispersive uniaxial media. Theoretical analysis on dispersion relation for plasma media reveals that the phase velocity is much larger than C when the refractive index is smaller than that in vacuum at special frequency. Based on the theory, we designed a metamaterial construction which is dispersive uniaxial and exhibiting Drude-model-like frequency dependence to realize the superluminal phase velocity. We also verified it through the experiment.
