Abstract:
Pulsar radio emission is not well understood because of a lack of knowledge about the emission geometry and the
plasma process involved. We develop a mechanism for pulsar radio emission that takes into account the detailed
viewing geometry of pulsars and the dipolar magnetic
fi
eld con
fi
guration. Using a suitably chosen geometry and
plasma parameters, we derive analytical expressions for the Stokes parameters of the radiation
fi
eld in the frame
centered on the neutron star. We have simulated pulse pro
fi
les based on our analytical formulation. It seems that we
can explain the enhanced radiation and most of the diverse polarization properties of radio pulsars. We have
estimated the brightness temperature, which seems to agree with the observations. The polarization angle predicted
by the model is in good agreement with the rotating vector model.
