OPTIMIZATION OF ARBITRARILY SHAPED DIELECTRIC AXISYMMETRIC HORNS THROUGH FINITE ELEMENTS AND THE ANNEALING ALGORITHM

摘要

This work addresses the design of dielectric axisymmetric horns with arbitrarily shape profile. The optimization is carried out by an adaptive version of the simulated annealing (SA) algorithm. In this way we avoid local minimum. No information about initial shape is introduced. The analysis is performed by a hybrid method based on the segmentation technique, the finite-element method and a matrix Lanczo-s-Pade algorithm (SFELP), adapted to problems with axial symmetry. A set of example designs are presented to verify the technique.
