EM-simulation-driven antenna design using multi-point response correction

A technique for (electromagnetic) EM-simulation-driven design optimization of antennas is presented. Our approach exploits coarse-discretization EM simulations as the low-fidelity model of the antenna under design, which is then aligned with the high-fidelity EM antenna model to be optimized using multi-point response correction. As opposed to the simple additive response correction (so-called output space mapping), the multi-point version utilizes all high-fidelity model data accumulated during the optimization process, which improves the generalization capability of the corrected model. As a result, the optimized antenna design can be obtained at a lower computational cost as demonstrated using the dielectric resonator antenna example.
