In this work, methodologies for low-cost and reliable microwave modeling are presented using variable-fidelity response features. The two key components of our approach are: 1) a realization of the modeling process at the level of suitably selected feature points of the responses (e.g., -parameters versus frequency) of the structure at hand and 2) the exploitation of variable-fidelity EM simulation...
This paper describes a novel approach to low-cost, accurate modeling of microwave structures using response features. Computational efficiency of the proposed method originates from the less nonlinear dependence of the feature points on the designable parameters of the structure of interest than conventionally used responses (e.g., S-parameters vs. frequency). Further decrease of the surrogate model...
A simple technique for accurate and low-cost modeling of microwave structures is presented. Our approach utilizes response surface approximation at the level of suitably selected response features rather than direct approximation of frequency responses (e.g., S-parameters) of the structure of interest. By exploiting the fact that dependence of the features on designable parameters is much less nonlinear...
