CAD of rectangular-waveguide H-plane circuits bysegmentation, finite elements and artificial neural networks

Rectangular waveguide H-plane circuits are efficiently analysed by the segmentation finite element method. Artificial neural networks, the computation times of which are very fast, are used to generalise the responses to different configurations. The analytic model obtained in this way is used in optimisation programs for microwave circuit design. Application of the method to a three cavity filter is presented.
