We study the variations of the refractive index of a moving homogeneous dispersive half‐space (cold plasma or conventional dielectric) under the incidence of a plane quasi‐monochromatic wave entering from vacuum. The medium is moving parallel or perpendicular to the boundary, and the plane of incidence, containing either the magnetic or the electric vector, has an arbitrary azimuthal orientation with respect to the velocity of parallel motion.
