Abstract
A global optimization method for the design of arbitrarily shaped H-plane passive waveguide devices is presented. An adaptive simulated annealing algorithm (SA) is used to avoid local minima. No information on the initial shape is introduced. A hybrid method based on the segmentation technique, the finite-element method, and a matrix Lanczos–Padé algorithm (SFELP) adapted to 2D space (2D SFELP) efficiently calculates the wideband response. Technological constraints and mechanical tolerances are taken into account in the design process. © 2005 Wiley Periodicals, Inc.
