We calculate the field distribution near focus of an aplanatic system for incident ASPBs with different polarization orders and initial azimuthal angles, and based on the simulation results, we find some unique focusing properties of the beams, such as ever on-axis energy null, strong longitudinal field, and flowerlike intensity distribution at focus.

Because of the dependence of rotating dipole PA curve on layer of field lines, it avoids the degeneracy problem of conventional rotating vector model that all layers of field lines have the same PA curve with fixed inclination and impact angles, therefore it provides a useful way to identify the emission from different layers and constrain the location of emission regions in pulsar magnetosphere by fitting the observed pulsar radio PA data with rotating dipole PA curve.
