Abstract
This contribution is concerned with the exact and asymptotic scattering of an oblique incident time-harmonic electromagnetic plane wave from a fast moving perfectly electric conducting wedge. By utilizing the Lorentz transformation and applying Maxwelln's boundary conditions in the (scatterer) co-moving frame, an exact solution for the total fields is obtained in both the co-moving (scatterer) and the laboratory (incident field) frames. The fields are evaluated asymptotically in the high frequency regime in which the scattered field is presented as a sum of three wave types: the direct (reflected) wave, a shadowing wave, and a diffraction wave. Novel relativistic wave phenomena that are associated with the scatterer dynamics are explored.
