A three‐dimensional (3D) finite‐difference time‐domain (FDTD) simulator is developed for the investigation of network ( S ‐) parameters of rectangular cross‐section waveguide filters. The simulator is calibrated against analytical LC equivalent models. Any number of horizontal or vertical windows can be located to act as capacitive or inductive irises, respectively, and two‐port filter characteristics can be obtained automatically. © 2013 Wiley Periodicals, Inc.
