Energy emission by moving charges

This paper analizes the power emitted by charges accelerated on general trajectories. The electric and magnetic field radiated are calculated in detail through the retarded potentials, and the non-relativistic, quasistatic and radiation regimes are treated. The radiated power is obtained through the calculation of the Poynting vector, and the two cases of linear and circular accelerators are analyzed. After this, the distribution in frequencies of this radiation is studied for a moving charge and a moving magnetic moment, and the intensity distribution in angles and frequencies is generalized to the case of a continuous set of charges in motion.
