WOLF, C.. Polarization rotation of electromagnetic waves by two abelian gauge fields coupled to torsion. Rev. mex. fis. [online]. 2004, vol.50, n.1, pp.49-52. ISSN 0035-001X.

By considering the coupling of two abelian gauge fields to pseudoscalar torsion we demonstrate that three different rotated polarized waves result for propagation over cosmological distances in a torsion field with constant gradient. It is also demonstrated that one of the waves is twice as intense as the other two providing us with a signature to identify the above coupling.
