Abstract

This paper presents an optimization process based on genetic algorithm (GA), for the design of band-pass filters in rectangular waveguides coupled by circular irises. The step discontinuities of the filters are treated by modal analysis and the S parameters are determinate to obtain the frequency response of the components. Higher order mode interactions between waveguide uniaxial discontinuities are rigorously considered in the design procedure. A genetic algorithm synthesis procedure is introduced to determine the optimal set of geometrical parameters required to yield better performances in pass-band and satisfy specifications for the optimized filters. The study combines advantageously the efficiency of the mode-matching method with the flexibility of GA.
