摘要：
This paper presents a general algorithm for the characterization and the optimization of coupled-cavity band-pass filters in metallic cylindrical waveguides using the Mode-Matching Method coupled to the Genetic Algorithm. The step discontinuities of the studied structures are treated and the S parameters are determinate to obtain the various frequency responses. Higher order mode interactions between waveguide uniaxial discontinuities are rigorously considered in the design procedure and a study on the convergence of modes is presented for the optimization of computational time. The genetic algorithm introduced is intended to evolve optimal structures parameters required to yield better performances in pass-band and satisfy specifications for the optimized filters.
