Half-wave plante non-idealities and realistic beams

We study systematic effects from half-wave plates (HWPs) for CMB experiments using full-sky time-domain beam convolution simulations. We investigate how different HWP configurations optimized for dichroic detectors centred at 95 and 150 GHz impact the reconstruction of primordial B-mode polarization.
