  A thermal active galactic nucleus (AGN) consist of a powerful, broad-band
continuum source that is surrounded by several reprocessing media with
different geometries and compositions. Here we investigate the expected
spectropolarimetric signatures in the optical/UV and X-ray wavebands as they
arise from the complex radiative coupling between different, axis-symmetric AGN
media. Using the latest version of the Monte-Carlo radiative transfer code
STOKES, we obtain spectral fluxes, polarization percentages, and polarization
position angles. In the optical/UV, we assume unpolarized photons coming from a
compact source that are reprocessed by an optically-thick, dusty torus and by
equatorial and polar electron-scattering regions. In the X-ray band, we
additionally assume a lamp-post geometry with an X-ray source irradiating the
accretion disk from above. We compare our results for the two wavebands and
thereby provide predictions for future X-ray polarimetric missions. These
predictions can be based on present-day optical/UV spectropolarimetric
observations. In particular, we conclude that the observed polarization
dichotomy in the optical/UV band should extend into the X-ray range.
