Giordano Scarciotti,Alessandro Astolfi is .. These are, in fact, necessary properties of the propagation direction in space–time of electromagnetic waves as a consequence of Maxwell’s source–free field equations. This fundamental property of electromagnetic radiation was discovered in 1956 by Ivor Robinson (presented first in a lecture

Since we envisage the source capable of arbitrary motion the ‘spherical’ wave fronts produced by it will in general be undergoing collisions and so the asymptotic limit we are looking for should, in general, be the colliding plane fro

The results are presented in the form of metric perturbations and also in the gauge invariant and covariant perturbation formalism. In these approximate models the p
