✦ Synopsis
A relevant automated electromagnetic (EM) optimization method is presented. This optimization method combines a rigorous and accurate global EM analysis of the device performed with a "nite element method (FEM) and a fast analytical model deducted from its segmented EM analysis applying a neural network approximation. First we present our optimization tools, then we describe our full EM optimization method with the de"nition of the analytical model. Afterward, we apply it to optimize three volumetric dielectric resonator (DR) "lters, considering the novel topology of the dual-mode "lter. The accuracy of this automated method is demonstrated considering the good agreement between theoretical optimization results and experimental ones.
