This paper first appeared in preliminary form as Report INFN/FM–96/01 (I.N.F.N.; Frascati, 1996), its number in the electronic LANL Archives being # physics/9610012; Oct. 15, 1996; cf. Ref. [24]Erasmo Recami Physica A: Statistical Mechanics and its Applications, 1998, vol. 252, issue 3, 586-610 Abstract: In this paper we extend for the case of Maxwell equations the “X-shaped” solutions previously found in the case of scalar (e.g., acoustic) wave equations. Such solutions are localized in theory: i.e., diffraction-free and particle-like (wavelets), in that they maintain their shape as they propagate. In the electromagnetic case they are particularly interesting, since they are expected to be Superluminal. We address also the problem of their practical, approximate production by finite (dynamic) radiators. Finally, we discuss the appearance of the X-shaped solutions from the purely geometric point of view of the Special Relativity theory.
