Electrodynamics of hyperbolically accelerated charges III. Energy-momentumof the field of a hyperbolically moving charge

We give a detailed description of the energy-momentum relationships of the Bondi Gold field. The Schott field is separated into a near field and a rad iation field. The physical significance of a plane acting as a barrier for transport of energy in the field of a charge with permanent hyperbolic moti on, but which lets energy through in the case of hyperbolic motion for a fi nite time interval, is discussed. We deduce general expressions for energy and momentum of the near field and radiation field of charges with arbitrar y motion. The field reaction on the particle producing the field is calcula ted. The formulae are applied to the Schott field and the Bondi Gold field. (C) 2000 Academic Press.
