Neural network models of slotted waveguide directional couplers

[摘要] ENGLISH ABSTRACT:The application of artificial neural networks to microwave circuits is investigated. A neuralnetwork model is developed for two parallel waveguides coupled by a longitudinal slot in thecommon broad wall. Training data is generated through a moment method solution of theintegral equations that describe the structure. A systematic investigation of training options iscarried out and the development of the model is described in detail. The model is evaluated andcompared with an Adaptive Sampling Interpolation (ASI) Technique. The neural network isfound to be less accurate than the ASI Technique at a much greater expense of development timeand required user supervision.
