Scalar pulsed beam scattering by a fast moving soft wedge

This contribution is concerned with deriving the scattering of a time dependent scalar pulsed beam from a moving wedge scatterer. The incident wave object serve as the basis wave propagators of the time dependent phase-space pulsed beam summation method which is a general framework for analyzing propagation of scalar and electromagnetic fields from extended sources. The scalar problem that is presented here describes the scattering of EM Hertz potentials from a PEC wedge. By utilizing the Lorentz Transformation and applying Maxwell´s boundary conditions in the (scatterer) co-moving frame, the short-pulsed asymptotic solution for the scattered potential is obtained in the laboratory frame.
