Abstract :
Challenges and solutions concerning the accurate electromagnetic simulations of large multi-reflector antennas for deep-space submillimeter-wave radioastronomy are considered. The current status of the ESA Planck HFI beam simulation is presented. Gaussian fitting of the computed beams is performed.
