Abstract
We report results of systematic analytic and numerical study of the electromagnetic field generated by a moving with the uniform velocity source through a dispersive lossy metamaterial. The Cherenkov radiation in a far zone is considered with the use of 2D stationary phase method. In our simulations the Drude model is implemented for a metamaterial. As a result of passage of modulated charged source in metamaterial a double branching of the Cherenkov cone with negative refractive index is registered.
