Energy characteristics of radiation of oscillating dipoles moving in a nondispersive medium and a cold plasma

We consider radiation of moving oscillating electric and magnetic dipoles, whose moments are oriented along their velocity. We have derived general expressions for field components and radiation power, which are valid for isotropic homogeneous nonabsorbing media. Special cases of a nondispersive medium and a cold plasma are considered. In these cases, the dependences of energy spectral distributions and radiation powers are analyzed as a function of the velocity of the sources and the parameters of media.
