Antenna Modeling using Space-Mapping Corrected Cauchy-Approximation Surrogates

An accurate and computationally cheap antenna modeling technique is presented. Our methodology is a two-stage approach. In the first step, a Cauchy-approximation model is created using the full-wave simulation data of the coarsely-discretized antenna structure. This model is further corrected using space mapping and a limited number of high-fidelity antenna simulations. We demonstrate that our approach allows us to obtain the modeling accuracy …
