Depolarization of Pulsar Radio Emission
arXiv:astro-ph/9908112 · doi:10.1086/312335
Abstract
We show that intensity dependent depolarization of single pulses (e.g., Xiluoris et al. 1994) may be due to the nonlinear decay of the "upper" ordinary mode into an unpolarized extraordinary mode and a backward propagating wave. The decay occurs in the innermost parts of the pulsar magnetosphere for obliquely propagating O waves.
