Electromagnetic scattering from a dielectric cylinder of finite length

The dyadic scattering amplitude is determined for a planar electromagnetic wave incident on a dielectric cylinder of finite length and circular cross section under the assumption that the internal fields induced within the finite-length cylinder can be approximated by those within an infinite-length cylinder. These internal fields are then used to calculate the dyadic scattering amplitude in terms of the cylinder´s physical dimensions, orientation, and dielectric properties. The theoretical development is complemented by numerical calculations, and its validity assessed by comparison with experiment
