In recent years, together with an international group of collaborators, we have been studying the radiation properties of pulsars within the framework of the PSG (Partially Screened Gap) model for the polar cap region of neutron stars, which we proposed. This model has proven effective in explaining the fundamental features of pulsar radio and X-ray emissions. We are currently working on the polarization properties of the observed emission. Importantly, the polarization characteristics of individual pulses play a crucial role in these studies. It appears that the most plausible mechanism that can explain the observed features is coherent curvature radiation. A significant portion of our scientific activity is devoted to this mechanism.
