Abstract
This article presents a computer‐aided synthesis technique for E‐plane and iris‐coupled waveguide bandpass filters. This technique uses fewer optimization variables than are required by the existing techniques. The designer begins with an accurate a priori knowledge of the search direction and uses an efficient penalty function. The closed‐form expressions for waveguide discontinuities, for the initial computation of the K‐inverter values in the optimization procedure, greatly enhances the design speed. The technique has been implemented on a personal computer and has been found to be as accurate as the existing methods implemented on mainframe computers. Results are presented for several Ku and Ka‐band iris‐coupled and E‐plane filters. © 1993 John Wiley & Sons, Inc.
