title: S approximation for light scattering by an infinitely long cylinder.
abstract: We obtain a simple expression for the scattering functions for perpendicular incidence in the main form of the S approximation for light scattered by an infinitely long, circular, dielectric cylinder. We numerically validate resulting expressions for extinction efficiency and scattered intensity against exact results.
