Abstract :
A method combining Infinite Impulse Response (IIR) filters and Neural Networks (NN) is proposed for modeling and optimizing Electromagnetic (EM) structures. This method is based on the characterization of the time response as a transfer function using a digital filter. The use of the neural network allows then the modeling of the geometric variation of the studied structure. The validity of our proposed technique is demonstrated on a step in width and a microstrip filter.
