Abstract


We report on rigorous physical optics simulations of the KSA Planck dual-reflector telescope being designed for measuring the temperature anisotropies and polarization characteristics of the cosmic microwave background. Both polarized mono-mode and non-polarized multi-mode beams covering the frequency range from 100 GHz to 857 GHz (D/λmin ∼ 5000) are computed by using a specially developed ultra-fast physical optics code propagating the source field mode-by-mode from the apertures of profiled corrugated horns simulated by the scattering matrix approach. Polarization characteristics of the broadband incoherent beams have been computed for the purpose of the analysis of systematic errors in polarization measurements.
