摘要
We consider the wavelength dependence of the ratio of the linear polarization degree to extinction (polarizing efficiency) for aligned spheroidal particles. Size/shape/orientation effects are analyzed. The comparison of the theory with the polarizing efficiency of the interstellar medium observed in several directions permits to restrict the range of the model parameters.
