Abstract :
Traditional optimization methods, such as Powell´s method and the Simplex Method (SM), are very difficult to the design of high performance filters in narrow relative bandwidth (BW). To improve the efficiency of the SM, we introduce a new optimization tool which is successfully applied to narrower bandwidth of four pole and six pole rectangular ridged waveguide filters.
