Alan, <><><> As I am told, and sort of understand dimly, the Green's function for the vector potential is (1/R) exp{-jkR} for all distances. It is only when you apply the differential operators to this vector potential form that you get near field components that fall off faster than 1/R. So, the question remains, is there really a Green's function for A with a near field component falling off faster than 1/R? That seems to be what MJU says is novel. <><><> Regards<><><> David.
