Abstract (IOPscience, SAO/NASA ADS, Zbl 0992.83065)
The Proca equation with negative masssquare is studied in a refractive and absorptive spacetime. The generation of superluminal radiation fields by subluminal currents is discussed. The possibility of timesymmetric wave propagation is analysed in the context of the WheelerFeynman absorber theory; it is shown how advanced modes of the Proca field can be turned into retarded ones in a permeable spacetime capable of producing an absorber field. A microscopic oscillator model for the permeability is suggested. Tachyonic LiénardWiechert potentials are studied and strictly causal retarded wave solutions are obtained. Energy transfer by superluminal radiation is discussed, and explicit formulae for the spectral energy density and intensity are derived. Superluminal radiation fields generated by classical damped oscillators carrying tachyonic charge are investigated, including the tachyonic analogue to Thomson and Rayleigh cross sections. The Maxwell equations for negative masssquare are derived, their nonlocal generalization to frequencydependent permeabilities, as well as the Poynting theorem for superluminal radiation in an absorptive spacetime.
