Experimental measurements of the light scattered from a metallic circular cylinder, with a section diameter comparable with the incident wavelength, upon a metallic flat substrate are presented. The validity of the theoretical numerical calculation obtained from a one-dimensional model based on Maxwell's coupled integral equations for real metals is demonstrated by comparison with the experimental results. The theoretical model is able to reproduce a geometric feature as the partial burying of the cylinder in the substrate because of the sputtering process.
