LIGHT-SCATTERING BY CLOSELY SPACED PARALLEL CYLINDERS EMBEDDED IN A SEMIINFINITE DIELECTRIC MEDIUM

A theory of light scattering by closely spaced parallel radially strat ified cylinders embedded in a semi-infinite dielectric matrix is prese nted. No restriction is placed on the polarization and direction of pr opagation of the incident plane wave. The diameter of the cylinders, t he spacing between the cylinders, and the incident wavelength are comp arable to each other. Each cylinder can have an arbitrary number of co ncentric layers of stratification, and the complex index of refraction in each layer can be different. A rigorous solution of Maxwell's equa tions that accounts for depolarization at oblique incidence, diffracti on of waves at the dielectric interface, and coherent scattering betwe en the cylinders is developed. The light-scattering characteristics of closely spaced cylinders in a dielectric medium are examined by numer ical data. (C) 1998 Optical Society of America.
