Abstract :
Far-IR space telescopes use horn antenna coupled bolometers for achieving high levels of sensitivity. Unfortunately at THz frequencies large cavity coupled horns prove significantly challenging to simulate accurately. This paper will outline alternative simulation concepts for such problems.
