Modeling an optically thick dusty torus with the half-opening angle θ_c = 30° relative to the symmetry axis combined with an electron-filled, equatorial disk with half-opening angle θ₀ = 10° measured from the equatorial plane. Top: polarization, P, as seen at different viewing inclinations, i; middle: the fraction, F/F_∗ of the central flux; bottom: the polarized flux PF/F_∗.
