Automated electromagnetic optimization method for microwave devices

We present a relevant automated electromagnetic (EM) optimization method which combines a fast analytical model deducted from a rigorous and accurate EM analysis and the global analysis of the device performed with a finite element method (FEM). We apply the automated method to the optimization of a volumic dielectric resonator filter. First, we present the definition of the analytical coarse model, then we use this model as a starting point for the EM optimization of structure dimensions. The accuracy of this automated method is then demonstrated, considering the good agreement between theoretical optimization results and experimental ones.
