ResumenA design approach for microwave waveguide filters with complicated response is proposed. It uses a combination of analytical filter synthesis theory, a very efficient"fullwave" analysis method of the structure and the Simulated Annealing (SA) optimization algorithm. Instead of a single optimization of the whole structure, the knowledge of the analytical synthesis of the filter allows todivide the optimization into more straightforward partial problems. In this way, the filter is segmented into sections that are optimized to match the partial frequency responses obtained from the analytical synthesis procedure. These optimized sections are a very useful starting point to overcome the difficulties of the final optimization of the whole structure. These ideas areapplied to the design of two waveguide filters with sophisticated response. The obtained results show the efficiency of the presented approach.
