A unified analytical description of the Cherenkov and complex Doppler phenomena in a simple metamaterial model is presented. It is shown that a moving monochromatic source generates radiation fields that exhibit features of both Doppler and Cherenkov effects. The theory presented explains many peculiar characteristics of Cherenkov radiation in left-handed metamaterials such as the backward direction of power emission, the constant radiation angle, and the lack of a velocity threshold. The theoretical findings are confirmed by numerical simulations based on the finite-difference time-domain method.
