A forward model for diffraction tomography is derived for the case of thin cylindrical objects by introducing a dyadic contrast function that takes into account depolarization phenomena, which were not previously addressed. As a result, polarimetric measurements may be used to distinguish between dielectric or metallic thin-cylindrical objects. In the case of metallic objects, it is also possible to reconstruct their direction.
