Abstract

It is argued that the observed properties of the intrinsically frequency-dependent polarization (FDP) in blazars suggest a one rather than a multi-component source model. Assuming a synchrotron origin of the emitted radiation, a well ordered magnetic field and a sharp break or cutoff in the electron distribution are both obligatory in such models; non-uniform pitch angle distribution or synchrotron losses enhance the resulting FDP. It is emphasized that the existence of such conditions in blazars finds observational support. Furthermore, a specific model is presented in order to illustrate the salient features of one-component models.
