| dc.description.abstract | In this paper we present a model to determine the light scattered by a metallic cylinder when it is illuminated with a light beam in oblique incidence. This model is based on an approximate solution to the Helmholtz-Kirchhoff integral by means of the Stationary Phase Method. The polarization of the beam, its width, and the misalignment between the beam and the cylinder are considered, as well as the reflection coefficient of the surface. | |
