文摘

This work uses an optimization technique for the frequency response of waveguide filters which is more advantageous than conventional waveguide filter optimization techniques. The method uses only three variables in the penalty function, irrespective of the filter order. It drastically reduces the chance of convergence to a local minimum, computer storage requirements and computation time. Several examples are presented to support the validity of the approach. The approach will be valuable in waveguide multiplexer design and in many other areas of engineering science.
