Abstract :
Step approximations for circular inductive posts in rectangular waveguides are calculated by conformal mapping, for use in mode matching computer programs which cannot handle curved surfaces. 300 parts per million accuracy is typical for resonant frequencies, requiring only two steps per 90° arc for large-radius posts
