A robust technique for microwave design optimization is presented. It is based on variable-fidelity electromagnetic (EM) simulations. The algorithm automatically switches between models of different fidelity taking into account the computational budget assumed for the design process. Additional mechanisms enhancing the algorithm include: frequency scaling to reduce the misalignment between the models of different fidelity; and the local response surface approximation to reduce the number of simulations. Our method is demonstrated using two filters and one antenna example.
