On superluminal light spots

The paper presents a model describing a moving emitter as a local polarization region which is produced by a light spot from a moving two-dimensional Gaussian beam and scans across a plane dielectric surface. The spectral composition, angular spectrum and the refraction, reflection, and polarization properties of such a beam are examined. The amplitude coefficients of refraction and reflection of the moving Gaussian beam are found and its total reflection behaviour and the total polarization angle are examined.
