Abstract
We have developed a model for pulsar polarization by taking into account of viewing geometry, rotation and modulation of the emission region. By solving for the plasma dynamics, we deduced the expressions for curvature radiation electric field in time as well as frequency domains. We show that both the 'antisymmetric' and 'symmetric' types of circular polarization are possible due to the combined effect of aberration, viewing geometry and modulation. We argue that aberration combined with modulation can introduce 'kinky' pattern into the PPA traverses.
