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…
The intense magnetic fields of neutron stars naturally lead to strong anisotropy and polarization of radiation emanating from their surfaces, both being sensitive to the hot spot position on the surface. Accordingly, pulse phase-resolved…
We combine the latest datasets obtained with different surveys to study the frequency dependence of polarized emission coming from Extragalactic Radio Sources (ERS). We consider data over a very wide frequency range starting from $1.4$ GHz…
