Wheeler-Feynman absorber theory

In terms of Wheeler-Feynman absorber theory [47] a standing wave, consisting of synchronized retarded and advanced components, originating at emitter and absorber respectively, constitutes the wave function of a photon and it extends over the entire region between emitter and absorber. 

If the superposition of point-source solutions is determined by a Green function , then by analogy with Wheeler-Feynman absorber theory the total interaction results from a symmetrical combination of retarded and advanced Green functions. On dehning these Green functions to be compatible with space-time geometry (Riemann tensor) the interaction is shown to be consistent with Einstein s field equations. 

This definition of an electromagnetic interaction corresponds exactly with the absorber theory of Wheeler and Feynman (1945). According to this theory an accelerated charge in otherwise charge-free space does not radiate...
