Antenna modeling using space‐mapping corrected cauchy approximation surrogates

Abstract In this work, a computationally efficient antenna modeling technique. Our methodology is a two‐stage approach is present. In the first stage, a Cauchy‐based approximation model is constructed using coarsely discretized full‐wave simulation. The accuracy of this model is improved using a space mapping (SM) approach. A limited number of high‐fidelity antenna simulations are used in the SM phase. We show that our approach obtains a …
