OPTICAL-PROPERTIES OF THIN DISCONTINUOUS METAL-FILMS

We present numerical calculations of the absorbance of light by a plane of metallic spheres. The absorbance is calculated as a function of frequency for s- and p-polarized light, for different angles of incidence and for different coverages. We demonstrate the importance of l-pole terms beyond the dipole (l = 1) term in interparticle scattering. We examine the effect of disorder and consider the influence of a dielectric substrate on the absorbance of the system consisting of a substrate plus adsorbed spheres.
