Abstract :
It is shown that a body of arbitrary material constitution, but invariant under a fixed rotation, must be periodic and will not depolarize when scattering in the backward or forward directions under linear polarization axial incidence if reciprocal, unless the least angle of invariance is 180/spl deg/. For circular polarization, the result is more general, the body will not depolarize even if it is not reciprocal.
