    abstract     = "A powerful optimization algorithm that incorporates Space Mapping (SM) and the new Output Space Mapping (OSM) to yield highly optimized results in a handful of fine model evaluations is presented.  The new method employs an {SM-}based interpolating surrogate (SMIS) framework that aims at matching the surrogate with the fine model locally.  Accuracy and convergence properties are demonstrated using a seven-section capacitively-loaded impedance transformer.  A highly optimized six-section {H-}plane waveguide filter design emerges after only four {HFSS} {EM} simulations, excluding necessary Jacobian estimations, using the new algorithm with sparse frequency sweeps."
