LIGHT SCATTERING BY TILTED CYLINDERS: PROPERTIES OF PARTIAL WAVE COEFFICIENTS.

An investigation is presented of relations among the partial-wave coefficients that describe scattering by infinite cylinders in terms of the parameters governing this process: the refractive index m, the size parameter x, and the tilting angle phi . A complete set of relations for nonabsorbing cylinders is presented, and their physical significance is discussed in terms of the principles of reciprocity and energy conservation. In particular, it is found that energy conservation for this nonspherical shape leads to additional constraints not present in the case of scattering by spheres.
