We report on rigorous physical optics simulations of the ESA 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/lambda(min) similar to 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 broad-band incoherent beams have been computed for the purpose of the analysis of systematic errors in polarization measurements.
