Abstract :
A new and simple surrogate modeling technique for microwave devices is presented. Our method exploits a recently introduced shape-preserving response prediction procedure that allows us to estimate the response (e.g., S-parameters over certain frequency range) of the computationally expensive microwave structure by examining the response of the computationally cheap (e.g., circuit equivalent) model of the structure. It is demonstrated that the proposed approach offers good modeling accuracy which is better than the accuracy provided by the space mapping approach, even when a very tight limit on the number of base designs used to set up a surrogate model is imposed.
