Paper Abstract

The existence of a specific wave object that arises when a spatially limited electromagnetic wave with abrupt leading edge propagates in vacuum is predicted. This object demonstrates a precursor-like behavior, since the diffractive spreading of the field proceeds behind it. The transverse structure and the field strength at the leading edge of the object remain unchanged during propagation, whereas its energy decreases as z-1 due to diffractive erosion of its trailing edge. This phenomenon to a certain extent resembles the Sommerfeld precursor formation in temporally dispersive medium.
