Electromagnetic radiation due to spacetime oscillations
Abstract
Wave equations are derived in the NewmanPenrose formalism for mixed electromagnetic and gravitational perturbations on both a flat spacetime background and a slightly charged ReissnerNordstrom background. The physical meaning of these equations is discussed and analytical results are derived for nonrelativistic sources and for ultrarelativistic particle motions. The relationship between evenparity (TM) electromagnetic radiation multipoles in the longwavelength approximation and static multipoles is shown to be the same as for classical radiation, suggesting a simple picture for electromagnetic radiation induced by gravitational perturbations.
