This paper presents a novel method for the analysis of large classes of microwave and mm‐wave passive components, including in‐line waveguide filters, single‐ and multi‐layer frequency selective surfaces, and open‐ended waveguide array antennas. This method is based on the segmentation technique, which permits us to reduce complex components to cascaded waveguide step discontinuities, which are separately characterized through their generalized impedance matrices, as calculated by the integral equation (IE) technique and the boundary integral‐resonant mode expansion (BI‐RME) method. Some examples demonstrate the flexibility and efficiency of the IE/BI‐RME method, and its utility in investigating novel structures not requiring costly fabrication techniques. © 2003 Wiley Periodicals, Inc.
