Ridged Waveguide Filter Optimization Using the Neural Networks and a Modified Simplex Method

Mohamed Yahia, Jun W. Tao, Hafedh Benzina and Mohamed N. Abdelkrim

Abstract—The rectangular ridged waveguide filter optimization is discussed. To improve the performances of the optimized filters, we exploit the height of the gaps between the ridges and the wave guide wall. We propose a hybrid technique, constituted by the artificial neural networks (ANNs) and the circuit theory. The proposed approach is applied to the design off our-pole and six-pole narrow band-pass filters. The results agree well with those produced by conventional simulators.

Index Terms—Rectangular ridged waveguides, filter optimization, multimodal variational method, artificial neuralnetworks.
